Response to comment on 'AIRE-deficient patients harbor unique high-affinity disease-ameliorating autoantibodies'
In 2016, we reported four substantial observations of APECED/APS1 patients, who are deficient in AIRE, a major regulator of central T cell tolerance (Meyer et al., 2016). Two of those observations have been challenged. Specifically, 'private' autoantibody reactivities shared by only a few patients but collectively targeting >1000 autoantigens have been attributed to false positives (Landegren, 2019). While acknowledging this risk, our study-design included follow-up validation, permitting us to adopt statistical approaches to also limit false negatives. Importantly, many such private specificities have now been validated by multiple, independent means including the autoantibodies ' molecular cloning and expression. Second, a significant correlation of antibody-mediated IFN a neutralization with an absence of disease in patients highly disposed to Type I diabetes has been challenged because of a claimed failure to replicate our findings (Landegren, 2019). However, flaws in design and implementation invalidate this challenge. Thus, our results present robust, insightful, independently validated depictions of APECED/APS1, that have spawned productive follow-up studies.Non peer reviewe
To Ki or Not to Ki: Re-Evaluating the Use and Potentials of Ki-67 for T Cell Analysis
This study discusses substantive advances in T cell proliferation analysis, with the aim to provoke a re-evaluation of the generally-held view that Ki-67 is a reliable proliferation marker per se, and to offer a more sensitive and effective method for T cell cycle analysis, with informative examples in mouse and human settings. We summarize recent experimental work from our labs showing that, by Ki-67/DNA dual staining and refined flow cytometric methods, we were able to identify T cells in the S-G2/M phases of the cell-cycle in the peripheral blood (collectively termed “T Double S” for T cells in S-phase in Sanguine: in short “TDS” cells). Without our refinement, such cells may be excluded from conventional lymphocyte analyses. Specifically, we analyzed clonal expansion of antigen-specific CD8 T cells in vaccinated mice, and demonstrated the potential of TDS cells to reflect immune dynamics in human blood samples from healthy donors, and patients with type 1 diabetes, infectious mononucleosis, and COVID-19. The Ki-67/DNA dual staining, or TDS assay, provides a reliable approach by which human peripheral blood can be used to reflect the dynamics of human lymphocytes, rather than providing mere steady-state phenotypic snapshots. The method does not require highly sophisticated “-omics” capabilities, so it should be widely-applicable to health care in diverse settings. Furthermore, our results argue that the TDS assay can provide a window on immune dynamics in extra-lymphoid tissues, a long-sought potential of peripheral blood monitoring, for example in relation to organ-specific autoimmune diseases and infections, and cancer immunotherapy

Autoimmunity: Is antigen-specific suppression now unsuppressed?
AbstractRecent studies suggest that putative regulatory lymphocytes can effect antigen-specific down-regulation of autoimmunity. But we have yet to see how much this improves our picture of autoimmune disease progression
Using art and history to communicate immunology to a broad audience.
Francesca Di Rosa works on T cells and is committed to science outreach. Together with Adrian Hayday, she recently conceptualized and delivered the exhibit ‘Vaccination, a time machine’ at the Royal Society Summer Exhibition in London. Here, she shares her thoughts on how to communicate a core scientific content with artistic and historical input, according to her ‘5C’ formula
Electrochemical-control of abrasive polishing and machining rates, U.S. Patent 6,171,467
An apparatus and method is disclosed; both of which use electrochemistry to selectively grow and remove hard oxide coatings on metals, and capacitive double layers on non-metals and semiconductors in order to predict and control the rate of surface abrasion during planarization of the surface of such materials
