    TRP Channels in Dental Pain

    No full text
    Despite the high incidence of dental pain, the mechanism underlying its generation is mostly unknown. Functional expression of temperature-sensitive transient receptor potential (thermo-TRP) channels, such as TRPV1, TRPV2, TRPM8, and TRPA1 in dental primary afferent neurons and TRPV1, TRPV2, TRPV3, TRPV4, and TRPM3 in odontoblasts, has been demonstrated and suggested as responsible for dental pain elicited by hot and cold food. However, dental pain induced by light touch or sweet substance cannot be explained by the role of thermo-TRP channels. Most of current therapeutics of dentin hypersensitivity is based on hydrodynamic theory, which argues that light stimuli such as air puff and temperature changes cause fluid movement within dentinal tubule, which is then transduced as pain. To test this theory, various TRP channels as candidates of cellular mechanotransducers were studied for expression in dental primary afferents and odontoblasts. The expression of TRPV1, TRPV2, TRPA1, TRPV4, and TRPM3 in trigeminal neurons and TRPV1, TRPV2, TRPV3, TRPV4 and TRPM3 in odontoblasts has been revealed. However, their roles as cellular mechanotransducers are controversial and contribution to generation of dental pain is still elusive. This review discusses recent advances in understanding of molecular mechanism underlying development of dental pain. © Chung and Oh; Licensee Bentham Open.N

    Impacts of glycans attached to therapeutic glycoproteins

    No full text
    High value-added therapeutic proteins have been leading the biologics industry and occupied major portion of the market. More than 60% of the currently available protein therapeutics are glycoproteins attached with glycans which play crucial roles for the protein folding, therapeutic efficacy, in vivo half-life and immunogenecity. This review introduces the process of glycosylation and the impacts of glycans in the aspects of therapeutics. The important glycan structures in therapeutic performances were also summarized focusing on three representative categories of glycoproteins, cytokines, therapeutic antibody and enzyme. Currently, mammalian expression systems such as Chinese hamster ovary cells are preferred for the production of therapeutic glycoproteins due to their ability to synthesize glycans having similar structures with human type glycans. However, recent advances of plant glycoengineering to overcome the limitation originating from different glycan structures will soon allow to develop more efficient and economic plant-based production systems for therapeutic glycoproteins.open
