  • endogenous
  • The dependence of human T-lymphocyte migration on the 5-lipoxygenation of endogenous arachidonic acid. (springer.com)
  • Access of antigen to the MHC class I presentation pathway was originally thought to be restricted to endogenous proteins, i.e., those expressed within the cytoplasm of the cell presenting the antigen. (rupress.org)
  • receptor
  • When T and B lymphocytes with the correct receptor undergo. (brainscape.com)
  • Discoveries since then initially revealed that MALT1 is a key adaptor molecule in antigen receptor signaling to the transcription factor NF-κB, which is crucial for lymphocyte function. (aacrjournals.org)
  • It increases Fc receptor density, increases the formation and release of reactive oxygen intermediates, increases the synthesis and release of complement cascade proteins, especially C2 and factor B, and increases class I1 (HLA-DR) antigen expression. (docme.ru)
  • migration
  • Thus, endoproteolytic cleavage regulates both homeostatic and activation-induced changes in cell surface L-selectin density, which directs the migration patterns of activated lymphocytes and neutrophils in vivo. (biomedsearch.com)
  • Expression
  • The mechanism by which low concentrations of GST stimulate HLA-DR antigen expression is unclear, but was shown by 35S-methionine cell labeliwg not to involve increased HLA-DR protein synthesis. (docme.ru)
