or actively by prior immunization of the recipient with graft antigens which evoke specific antibodies and form antigen-antibody complexes which bind to the antigen receptor sites of the T-cells and block their cytotoxic activity. (lookformedical.com)
The S1 subunit contains a receptor binding domain or RBD that binds with the specific receptors, while the S2 subunit helps membrane fusion. (openaccesspub.org)
The crucial step of receptor binding depends on the closed and open conformations of the S-Protein ectodomain trimer 10 , 11 . (openaccesspub.org)
In analogy with histo-blood group A antigen, Forssman (Fs) antigen terminates with α3- N -acetylgalactosamine and can be used by pathogens as a host receptor in many mammals. (ashpublications.org)
The Receptor Binding Domain (RBD) of Spike protein recognizes and attaches to the Angiotensin-Converting Enzyme 2 (ACE2) receptor found on the surface of type I and II pneumocytes, endothelial cells, and ciliated bronchial epithelial cells. (herpes-pics.com)
Protein5
In this experiment, we observed cytokine gene expression changes in Gallus gallus embryo after challenge with Delta SARS-CoV-2 RBD spike protein antigen, from a concentration of 10 µg/mL to a series of highly diluted forms in ethanol, along with controls. (openaccesspub.org)
This host-specific binding of the spike protein initiates coronavirus infection. (openaccesspub.org)
These include Epstein-Barr nuclear antigen (EBNA)-1, EBNA-2, EBNA-3A, EBNA-3B, EBNA-3C, EBNA-leader protein (EBNA-LP) and latent membrane proteins (LMP)-1, LMP-2A and LMP-2B and the Epstein-Barr encoded RNAs (EBERs). (wikidoc.org)
EBNA-1 protein binds to a replication origin (oriP) within the viral genome and mediates replication and partitioning of the episome during division of the host cell. (wikidoc.org)
The key to this kit is the high sensitivity of detection of bound Fc-tagged Spike protein by HRP-labeled Anti-Fc. (herpes-pics.com)
A new histo-blood group system was discovered, based on the identification of Forssman glycolipid antigen on human red blood cells. (ashpublications.org)
Spike1
The natural binding of coronaviruses' spike (S) glycoprotein occurs with various receptors - ACE2, APN, DPP4, CEACAM, Sia, and O-acSia of human cells. (openaccesspub.org)
Specific3
It may be nonspecific as in the administration of immunosuppressive agents (drugs or radiation) or by lymphocyte depletion or may be specific as in desensitization or the simultaneous administration of antigen and immunosuppressive drugs. (lookformedical.com)
In our body, the function of T cells and B Cells is to recognize specific non-self antigens, during a process known as antigen presentation. (wellnessadvantage.com)
The approximate areas of the HSV-2 genes encoding HSV-2 type-specific CD4+ antigens have been decided through the use of HSV-1 x HSV-2 intertypic recombinant virus and embrace the approximate map areas 0.30 to 0.46, 0.59 to 0.67, 0.67 to 0.73, and 0.82 to 1.Zero items. (herpes-pics.com)
Gene3
Attogram and zeptogram level concentrations of the antigen showed consistently remarkable up-regulation of INF-α among different cytokine gene expressions. (openaccesspub.org)
INF-β gene expressions at the zeptogram level of the antigen showed consistent changes, although not so outstanding. (openaccesspub.org)
EBNA-1 possesses a glycine - alanine repeat that impairs antigen processing and MHC class I-restricted antigen presentation thereby inhibiting the CD8-restricted cytotoxic T-cell response against virus infected cells. (wikidoc.org)
Form1
Following activation, B cells and T cells leave a lasting legacy of the antigens they have encountered, in the form of memory cells. (wellnessadvantage.com)
Alternative1
Antigens that exist in alternative (allelic) forms in a single species. (lookformedical.com)
