WebThe other sites were localized through study of the antigenic activity of fragments generated by controlled cleavage of the native protein with different endopeptidases. Two identified cleavage products of 26K and 13K, immunoreactive to site A-B- and site D-specific MAbs respectively, could be aligned on the S primary structure according to N-terminal … Web21 de dez. de 1999 · In many antigen-presenting cells these processes occur in intracellular endosomal compartments, where peptides are generated and loaded onto class II MHC proteins for subsequent transport to the surface and presentation to T cells. Here, we provide evidence for an additional antigen-processing pathway in immature dendritic …
WebAbstract. The introduction of antigen into tissues can induce an inflammatory response initiated by antigen-specific T lymphocytes. Central to this process is the recognition of antigen by specific T cells that cannot respond to intact antigen directly, but rather recognize antigenic fragments in association with gene products of the major ... WebGenerally, antigens are foreign proteins or their fragments that enter host body via an infection. However, in some cases, the body’s own proteins may act as antigens and …
