  • stimulation
  • The present study was conducted to determine whether the stress of physical work further affects the expression of splenic lymphocyte phenotypes following in vitro stimulation by the T-cell mitogen, Con A, and also by interleukin-1 (IL1). (biomedsearch.com)
  • There was a significant effect of stimulation by Con A on the percentage of splenic lymphocytes positive for Thy1.2, Lyt-2, L3T4, and goat anti-mouse Ig, regardless of treatment condition. (biomedsearch.com)
  • No significant changes are detected after PHA or ConA stimulation while LPS and PWM stimulated cultures after 18-48h show decreased number of antigen-positive cells but in final terms of cultivation antigen is expressed again. (biotium.com)
  • TI-1 antigens have an intrinsic B cell activating activity, that can directly cause proliferation and differentiation of B lymphocytes without T cell stimulation and independently of their BCR specificity. (wikipedia.org)
  • Macrophages
  • The protein is expressed in lymphocytes, neutrophils, macrophages, and endothelium and may regulate neutrophil motility, adhesion to fibrinogen matrix proteins, and transendothelial migration. (wikipedia.org)
  • This causal lentivirus can be found in monocytes, lymphocytes and macrophages of infected sheep in the presence of humoral and cell mediated immune response and can also be detected by conducting several serological tests. (wikipedia.org)
  • MR is involved in recognizing the surface of pathogens and is involved in phago- and endocytosis and mediating antigen processing and presentation in a variety of cells including monocyte/macrophages and endothelial cells. (wikipedia.org)
  • cytokines
  • Natural Killer T (NKT) cells are activated by CD1d-presented antigens, and rapidly produce Th1 and Th2 cytokines, typically represented by interferon-gamma and IL-4 production. (wikipedia.org)
  • Even though the response on TI antigens is not dependent on T lymphocytes, there are some cytokines, produced mainly by T lymphocytes and natural killer (NK) cells, necessary for eliciting reaction against these antigens. (wikipedia.org)
  • Lymphotoxin-alpha (LT-alpha) and lymphotoxin-beta (LT-beta), two related cytokines produced by lymphocytes that are cytotoxic for a wide range of tumor cells in vitro and in vivo. (wikipedia.org)
  • helper
  • Bcl6 and Blimp-1 are reciprocal and antagonistic regulators of T follicular helper cell differentiation. (yale.edu)
  • However bacterial polysaccharides and lipopolysaccharides, and some polymeric proteins, can stimulate B lymphocytes without involvement of helper T cells. (wikipedia.org)
  • Molecular
  • CD48 and CD2 molecular coupling together with other interaction pairs of CD28 and CD80, TCR and peptide-MHC and LFA-1 and ICAM-1 contribute to the formation of an immunological synapse between a T cell and an antigen presenting cell. (wikipedia.org)
