Available in PDF, EPUB and Kindle. Book excerpt: Major histocompatibility complex (MHC) class I and II proteins are intracellular receptors that bind peptides derived from endogenous and exogenous proteins, resp., and display them on the cell surface for surveillance by T cells of the immune system. The presented peptides help the T cells to discriminate between self and non-self and to eliminate the pathogen infected or abnormal cells. After their synthesis, both class I and II molecules first bind suboptimal low-affinity ligand peptides and only later exchange them for high-affinity ones. For this exchange process, most class I and II molecules need the assistance of specific helper chaperones (tapasin and HLA-DM, resp.), the exact role of which is not well understood. In my thesis work, I have studied the molecular mechanism of peptide binding to MHC molecules with biochemical and computational methods, with a special emphasis on the mechanism of action of the helper chaperones. A comprehensive understanding of this process promises important clinical applications, for example in the development of new vaccines against viruses and in the suppression of autoimmune disorders

Download or read book MHC Molecules Expression Assembly and Function written by Robert G. Urban and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: 3 nant expression systems have been used to make MHC molecules con taining a single peptide of interest. To date, fifteen single peptide class I structures (incorporating three different HLA and two different H-2 allotypes/isotypes) and four additional class II structures (two single peptide complexes and two superantigen complexes) have been reported. These advances have enabled us to study the atomic detail of antigen presentation and the general mechanisms behind peptide binding, and begin to construct models of T cell recognition. Another area of research which has exploded over the past five years has been the identification of MHC-associated peptides. There are several methods one can use to determine the sequence identity of MHC restricted peptides. Historically, the most successful technique, albeit crude and encumbered with serious limitations, has been the use of overlapping synthetic peptides and T cell clones. Unfortunately, this method absolutely requires: (i) knowledge of the target antigen; (ii) availability of T cell clones; and (iii) a relatively short overall length for the target source protein, such that a set of overlapping pep tides can be affordably synthesized. Briefly, the entire sequence of the tar get protein is chemically synthesized using overlapping peptides which are then screened for biological activity using standard T cell presen tation assays. Despite its limitations, this method was used to identify the first immunodominant epitopes reported in the literature and con tinues to be used successfully today.

This book was released on 2017-03-27 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: T cells play a vital role mediating adaptive immunity, a specific acquired resistance to an infectious agent produced by the introduction of an antigen. There are a variety of T cell types with different functions. They are called T cells, because they are derived from the thymus gland. This volume discusses how T cells are regulated through the operation of signaling mechanisms. Topics covered include positive and negative selection, early events in T cell receptor engagement, and various T cell subsets.

Download or read book Molecular Evolution of the Major Histocompatibility Complex written by Jan Klein and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: From molecules to populations and back In biology, the most vigorous organisms often ensue from a union of two disparate, pure lines. In science, too, laws of hybrid vigor seem to operate at the interface between two disciplines, an interface that often proves to be fertile ground for germinating concepts and new outlooks. The fringes of research into the major histocompatibility complex (Mhc) have provided such an interface several times in the past and the encounters have invigorated fields such as transplantation biology, cellular immunology, and immunogenetics. In the last few years, a new interface has been emerging between Mhc and evolutionary genetics, and particularly the branch of evolutionary genetics dealing with molecular evolution. Mhc research relies upon molecular evolutionary genetics, with its grand superstructure of mathematical formulations, to come to grips with the events leading to and maintaining the Mhc polymorphism. Without the armament of rigorous statistical procedures developed by evolutionary geneticists, the intricate relationships among Mhc genes cannot be resolved. It will undoubtedly be a molecular geneticist who is the final arbiter in the dispute concerning the nature of the selection pressure molding the Mhc genes. And it is doubtful whether the true function of Mhc can ever be comprehended without the vantage point afforded by the elucidation of its evolutionary history.

Download or read book Peptide Therapeutics written by Ved Srivastava and published by Royal Society of Chemistry. This book was released on 2019-08-28 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: Peptide therapy has become a key strategy in innovative drug development, however, one of the potential barriers for the development of novel peptide drugs in the clinic is their deficiencies in clearly defined chemistry, manufacturing and controls (CMC) strategy from clinical development to commercialization. CMC can often become a rate-limiting step due to lack of knowledge and lack of a formal policy or guidelines on CMC for peptide-based drugs. Regulators use a risk-based approach, reviewing applications on a case-by-case basis. Peptide Therapeutics: Strategy and Tactics for Chemistry, Manufacturing, and Controls covers efficient manufacturing of peptide drug substances, a review of the process for submitting applications to the regulatory authority for drug approval, a holistic approach for quality attributes and quality control from a regulatory perspective, emerging analytical tools for the characterisation of impurities, and the assessment of stability. This book is an essential reference work for students and researchers, in both academia and industry, with an interest in learning about CMC, and facilitating development and manufacture of peptide-based drugs.
