    Beyond certification: assessing the domino effect of b corps in the coffee industry

    No full text
    This study seeks to find out whether the certification of coffee companies inspires other coffee companies to become B Corp certified too, thereby causing a so-called ‘domino effect’. Using data which B Lab provided as well as semi-structured interviews, the author finds no evidence for such a domino effect. However, B Corps, through the changes they implement as a result of their certification, seem to inspire others - within and outside of their value chain – to improve their practices. This study thus establishes a new theoretical foundation for B Corp’s impact through systemic change

    Molecular mechanisms of melanosome exocytosis

    Skin pigmentation relies on the pigment melanin and ensures photoprotection against ultraviolet (UV) radiation, avoiding the onset of skin cancers. Melanin is synthesized by melanocytes and stored within organelles designated melanosomes, which are tethered to actin in melanocyte dendrites through Rab27a, and finally transferred to keratinocytes. While the molecular players involved in melanogenesis have been extensively studied, those underlying melanosome exocytosis and melanin transfer remain unclear. Previously, our group found that Rab11b regulates melanin secretion and transfer in human skin. Here, we demonstrated that soluble factors, but not extracellular vesicles, present in keratinocyte-conditioned medium (KCM) stimulate melanin secretion from melanocytes, and transfer to keratinocytes. Moreover, we found that these factors are released by differentiated keratinocytes, but not by undifferentiated ones. Importantly, we ruled out the possibility that KCM increases melanin secretion and transfer as a consequence of increased melanin synthesis. For this, we quantified intracellular melanin levels in melanocytes cultured with or without KCM. Additionally, we confirmed that KCM does not increase the expression of microphthalmia-associated transcription factor (MITF) and its downstream transcript which encodes for tyrosinase in melanocytes, both required for melanogenesis. We also demonstrated that Rab3a, but not Rab11b, regulates KCM-stimulated melanin secretion and transfer, and shows enhanced colocalization with melanosomes in melanocyte dendrites upon incubation with KCM. Therefore, our results suggest that soluble factors released by differentiated keratinocytes control skin pigmentation by promoting the accumulation of Rab3a-positive melanosomes in melanocyte dendrites, and their release and subsequent transfer to keratinocytes. Furthermore, we found that Rab27a and the Rab3a guanine nucleotide exchange factor (Rab3il1) regulate KCM-stimulated melanin secretion. We also observed that Ca2+ -dependent signaling enhances KCM-induced melanin secretion, which raises a possible role for the Ca2+ -dependent Munc13-2 and Munc18-3 priming proteins in this process. Interestingly, immunoprecipitation and immunofluorescence assays suggested that Rab3a interacts with Rab27a on melanosome membranes, in the dendrites of KCM-stimulated melanocytes. Besides the characterization of the molecular machinery regulating KCM-induced melanin secretion, we identified a soluble factor present in KCM responsible for the stimulatory effect. Indeed, our results showed that KCM soluble factor(s) with a molecular weight lower than 3 KDa (< 3 KDa) is (are) the main stimulatory molecules in melanin secretion. Curiously, NMS-23-01 was abundantly detected in KCM < 3 KDa fraction by ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) analysis. Moreover, melanocytes cultured with NMS-23-01 demonstrated a dose-dependent increase in secreted melanin levels and a decrease in intracellular melanin content. Furthermore, the incubation of NMS-23-01 in both two-dimensional melanocyte/keratinocyte co-cultures and three-dimensional reconstructed human pigmented epidermises enhanced melanin transfer and augmented epidermal pigmentation. Thus, our results identified NMS-23-01 as the first molecule that increases skin pigmentation by specifically enhancing melanin secretion and subsequent transfer to keratinocytes. Importantly, NMS-24-01 (a specific antagonist of NMS-23-01) impaired both NMS-23-01 and KCM-stimulated melanin secretion levels. Additionally, we found that NMS 23-01 and KCM share the same molecular pathway of stimulated melanin secretion, independent of Rab11b and dependent of Rab27a, Rab3a and Rab3il1. Overall, our results suggest that NMS-23- 01 is at least one of the KCM soluble factors that stimulate melanin secretion. Furthermore, our studies indicate that two distinct pathways of melanosome exocytosis exist in melanocytes: a basal pathway controlled by Rab11b and another route controlled by the Rab27a-Rab3il1-Rab3a cascade, and triggered upon stimulation with NMS-23-01 (and possibly other small keratinocyte-derived soluble factors). Thus, this study contributed to a better understanding of fundamental processes of skin pigmentation, namely the molecular players involved in the stimulation of melanin secretion. Moreover, NMS-23-01 and its antagonist NMS-24-01 were identified in our work as novel and specific compounds to target melanin secretion and transfer. Therefore, they exhibit the potential to modulate skin color and serve as the basis of novel therapeutic strategies for hypo/hyperpigmentation disorders, potentially also with cosmetic applications. Importantly, the knowledge about NMS-23-01 and the molecular mechanisms stimulating melanin secretion and transfer can also be applied to stimulate skin tanning and photoprotection against UV-induced DNA damage.A pigmentação da pele depende do pigmento melanina, que assegura a fotoproteção contra a radiação ultravioleta (UV), evitando o desenvolvimento de cancros de pele. A melanina é sintetizada por melanócitos e armazenada em organelos designados melanossomas, que se ligam ao citoesqueleto de actina nas dendrites dos melanócitos através de Rab27a, sendo posteriormente transferidos para os queratinócitos. Embora os intervenientes moleculares envolvidos na melanogénese tenham sido extensivamente estudados, os mecanismos subjacentes à exocitose dos melanossomas e à transferência de melanina permanecem pouco claros. Anteriormente, o nosso grupo descobriu que Rab11b regula a secreção e a transferência de melanina na pele humana. Aqui, demonstramos que fatores solúveis, mas não vesículas extracelulares, presentes no meio condicionado por queratinócitos (KCM) estimulam a secreção de melanina a partir dos melanócitos e a sua transferência para os queratinócitos. Além disso, descobrimos que esses fatores são libertados por queratinócitos diferenciados, mas não pelos não diferenciados. Importa salientar que descartámos que o KCM aumenta a secreção e a transferência de melanina como consequência de um aumento da síntese deste pigmento. Para esse propósito, quantificámos os níveis de melanina intracelular em melanócitos cultivados com ou sem KCM. Confirmámos ainda que o KCM não aumenta a expressão do fator de transcrição associado à microftalmia (MITF), nem do seu transcrito que codifica para a tirosinase nos melanócitos, ambos necessários para a melanogénese. Demonstrámos também que Rab3a, mas não Rab11b, regula a secreção e transferência de melanina estimulada por KCM, apresentando um aumento da colocalização com os melanossomas nas dendrites dos melanócitos após incubação com KCM. Portanto, os nossos resultados sugerem que fatores solúveis libertados por queratinócitos diferenciados controlam a pigmentação da pele, promovendo a acumulação de melanossomas positivos para Rab3a nas dendrites dos melanócitos, bem como a sua libertação e subsequente transferência para os queratinócitos. Além disso, descobrimos que a Rab27a e o fator de troca de nucleotídeos de guanina da Rab3a (Rab3il1), também regulam a secreção de melanina estimulada por KCM. Observámos igualmente que a sinalização de Ca2+ potencia a secreção de melanina induzida por KCM e sugerimos uma possível função neste processo para as proteínas de priming dependentes de Ca2+ , nomeadamente Munc13- 2 e Munc18-3. Curiosamente, os nossos ensaios de imunoprecipitação e imunofluorescência sugerem que Rab3a e Rab27a interagem na membrana do melanossoma, nas dendrites dos melanócitos estimulados com KCM. Para além da caracterização da maquinaria molecular que regula a secreção de melanina induzida por KCM, identificámos um fator solúvel presente neste meio condicionado responsável por esse efeito estimulatório. Os nossos resultados demonstraram que o(s) fator(es) solúvel(is) do KCM com um peso molecular inferior a 3 KDa (< 3 KDa) estimula(m) a secreção de melanina. Curiosamente, a molécula NMS-23-01 foi detetada em abundância no KCM < 3 KDa através de análise por cromatografia líquida de ultra-alta performance acoplada a espectrometria de massa tandem (UHPLC-MS/MS). Melanócitos cultivados com NMS-23-01 demonstraram um aumento dependente da dose nos níveis de melanina secretada e uma diminuição no conteúdo de melanina intracelular. Além disso, a incubação de NMS-23-01 tanto em coculturas de melanócitos/queratinócitos como em epiderme humana pigmentada reconstruída aumentou a transferência de melanina e a pigmentação da epiderme. Assim, os nossos resultados identificaram NMS-23-01 como a primeira molécula que aumenta a pigmentação da pele especificamente através de um aumento na secreção de melanina e a sua subsequente transferência para os queratinócitos. Importa salientar que NMS-24-01 (um antagonista específico de NMS-23-01) inibiu os níveis de secreção de melanina estimulados tanto pela NMS-23-01, como pelo KCM. Adicionalmente, descobrimos que a NMS-23-01 e o KCM partilham a mesma via molecular de secreção de melanina, independente de Rab11b e dependente de Rab27a, Rab3a e Rab3il1. No geral, os nossos resultados sugerem que a NMS-23-01 é, pelo menos, um dos fatores solúveis presentes no KCM que estimulam a secreção de melanina. Os nossos resultados também indicam que existem duas vias distintas de exocitose de melanossomas nos melanócitos: uma via basal controlada por Rab11b e outra via controlada pela cascata Rab27a-Rab3il1-Rab3a, que é desencadeada sob estimulação com NMS-23-01 (e possivelmente por outros pequenos fatores solúveis derivados dos queratinócitos). Assim, este estudo contribuiu para uma melhor compreensão dos processos fundamentais da pigmentação cutânea, nomeadamente dos intervenientes moleculares envolvidos na estimulação da secreção de melanina. Além disso, NMS 23-01 e o seu antagonista NMS-24-01 foram identificados no nosso trabalho como compostos inovadores e específicos para regular a secreção e transferência de melanina. Portanto, podem eventualmente ser utilizados para modular a cor da pele e servir como base para novas estratégias terapêuticas para doenças de hipo/hiperpigmentação, tendo também possíveis aplicações cosméticas. É importante destacar que o conhecimento sobre NMS-23-01 e os mecanismos moleculares que estimulam a secreção e transferência de melanina pode ser também aplicado para promover o bronzeamento da pele e a fotoproteção contra danos no DNA induzidos pela radiação U

    Breaking BIN1 : investigating mechanisms of synaptic dysfunction in Alzheimer’s disease

    No full text
    Abstract Amyloid-β (Aβ) production is one of the earliest pathological alterations in the Alzheimer’s disease (AD) patients’ brain and has been the primary focus of therapeutic research. Yet, synapse loss best correlates with cognitive decline in AD; therefore, identifying the mechanisms driving synapse dysfunction should become a major therapeutic target. BIN1, an endocytic regulator and a significant risk gene for in late-onset AD (LOAD), has an unclear synaptic role. Our previous studies linked Bin1 to the endocytic recycling of BACE1, thereby leading to BACE1 accumulation and increased Aβ42 production. We have shown that mutations in Bin1 associated with LOAD, rs754834233 (PL) and rs138047593 (KR), lead to Bin1 loss of function in amyloidogenesis. However, Bin1’s synaptic function is ill-defined, with evidence suggesting roles at both presynaptic and postsynaptic sites that could affect synaptic transmission. Indeed, two previous studies suggest that Bin1 regulates the synaptic vesicle (SV) cycle, especially during SV release. After SV release, SV endocytic recycling involves compensatory endocytosis and SV reformation from an intermediate endosomal compartment, which requires scission and may depend on Bin1 activity. Moreover, we hypothesized that this function might be disrupted by the LOAD mutations, leading to synapse dysfunction. In this study, we assessed Bin1 function in inhibitory and excitatory synapses in primary mouse cortical neuron cultures. We found that Bin1 localizes presynaptically and has a crucial role in inhibitory synapses by regulating the SV exocytosis and endocytosis. Bin1 knockdown reduced synaptic endosome size in inhibitory neurons, likely by increasing SV exocytosis and endocytosis. In contrast, Bin1 knockdown only reduced exocytosis in excitatory neurons. Interestingly, inhibitory synapse loss was not rescued by the LOAD-associated Bin1 mutants or Aβ inhibition. Our results support that Bin1 loss of function may disrupt synapses prior to Aβ-dependent synapse dysfunction. Using immunoprecipitation coupled with mass spectrometry-based proteomic analysis, we found that the LOAD mutations disrupted Bin1 interactions, particularly with partners related to the SV cycle, actin dynamics, and intracellular trafficking. Using coimmunoprecipitation and proximity ligation assay, we confirmed that Bin1 mutants exhibited reduced interaction with regulators of SV cycle, VAMP2, SV2, dynamin, clathrin, and synaptojanin-1. Notably, clathrin overexpression restored GABAergic synapse density in Bin1 knockdown neurons, underscoring Bin1’s crucial role in the clathrin-mediated SV cycle. Bin1 knockdown increased neuronal hyperexcitability, likely due to the loss of inhibitory synapse function. This effect was mitigated by the antiepileptic levetiracetam, suggesting that Bin1 risk variants may lower the threshold for the development of seizures and contribute to AD development. Collectively, these findings suggest that the Bin1 mutation’s main impact is on the regulation of inhibitory synapse function, possibly contributing to the synaptic defects observed in Alzheimer’s disease.Resumo A produção de amiloide-β (Aβ) é uma das alterações patológicas mais precoces no cérebro de pacientes com doença de Alzheimer e tem sido o principal foco de investigação terapêutica. No entanto, a perda de sinapses correlaciona-se melhor com o declínio cognitivo na doença de Alzheimer; portanto, identificar os mecanismos que impulsionam a disfunção sináptica deve tornar-se um importante alvo terapêutico. BIN1, um regulador endocítico e um gene de risco significativo para Alzheimer de início tardio, tem um papel sináptico pouco claro. Os nossos estudos anteriores implicaram o Bin1 na reciclagem endocítica de BACE1, levando à acumulação de BACE1 e ao aumento da produção de Aβ42. Demonstrámos que mutações no Bin1 associadas à Alzheimer de início tardio, rs754834233 (PL) e rs138047593 (KR), levam à perda de função do Bin1 na amiloidogénese. No entanto, a função sináptica do Bin1 está mal definida, com alguma evidência de função nos compartimentos pré-sináptico, mas também no pós-sináptico que podem afetar a transmissão sináptica. De facto, os primeiros estudos sugeriam que o Bin1 regula o ciclo das vesículas sinápticas, especialmente na libertação das vesículas. Após a exocitose, a reciclagem endocítica das vesículas sinápticas envolve endocitose compensatória e reconstituição das vesículas a partir de um endossoma intermediário, o que requer sisão que pode depender da atividade do Bin1. Além disso, propomos a hipótese que essa função pode ser perturbada pelas mutações no Bin1, levando à disfunção sináptica. Neste estudo, avaliámos a função do Bin1 nas sinapses inibitórias e excitatórias em culturas primárias de neurónios corticais de ratinho. Descobrimos que o Bin1 se localiza pré-sinapticamente e tem um papel crucial nas sinapses inibitórias, regulando a exocitose e a endocitose de vesiculas sinápticas. A redução do Bin1 diminuiu o tamanho dos endossomas sinápticos em neurónios inibitórios, provavelmente pelo aumento da exocitose e a endocitose. Em contraste, quando diminuída a sua expressão Bin1 apenas reduziu a exocitose em neurónios excitatórios. Curiosamente, os mutantes de Bin1 associados a Alzheimer de início tardio não recuperaram a perda de sinapses inibitórias, e sendo esta perda insensível à inibição de Aβ. Os nossos resultados suportam que a perda de função do Bin1 pode prejudicar as sinapses antes de Aβ. Usando imunoprecipitação acoplada à análise proteómica baseada em espectrometria de massa, descobrimos que as mutações no Bin1 perturbam o seu interatoma, particularmente relacionado com o ciclo das vesículas sinápticas, dinâmica de actina e tráfego intracelular. Usando co-imunoprecipitação e ensaio de ligação por proximidade, confirmámos que os mutantes do Bin1 apresentaram interação reduzida com VAMP2, SV2, dinamina, clatrina e sinaptojanina-1. Notavelmente, a sobrerexpressão de clatrina restaurou a densidade de sinapses GABAérgicas em neurónios com expressão reduzida de Bin1, ressaltando o papel crucial do Bin1 na reciclagem de vesiculas sinápticas mediada por clatrina. A redução do Bin1 aumentou a hiperexcitabilidade neuronal, provavelmente devido à perda de sinapses inibitórias. Este efeito foi mitigado pelo antiepilético levetiracetam. Concluímos que as que variantes de risco do Bin1 podem diminuir o limiar para o desenvolvimento de convulsões e contribuir para o desenvolvimento da doença de Alzheimer. Coletivamente, descobrimos que as mutações no Bin1 prejudicam a sua capacidade de regular a função sináptica inibitória, potencialmente contribuindo para os defeitos sinápticos observados na doença de Alzheimer
