- Blocking the interaction of the immune checkpoint molecule programmed cell death protein-1 and its ligand, PD-L1, using specific antibodies has been a major breakthrough for immune oncology. (snmjournals.org)
Cell12
- Cell-surface expression and immune receptor recognition of HLA-B27 homodimers. (ox.ac.uk)
- Experiments with transfected cell lines demonstrated that KIR3DL1 and KIR3DL2, and immunoglobulin-like transcript 4 (ILT4), but not ILT2, are receptors for HLA-B27 homodimers. (ox.ac.uk)
- This study investigated the link between GM and the intrahepatic T cell receptor (TCR) immune repertoire (IR), and whether GM modulates the intrahepatic immune microenvironment via TCR IR during liver fibrosis. (frontiersin.org)
- After binding of a suitable antigen to the receptor, a signalling pathway is triggered inside the T cell that arms the cell for the respective task. (nanotech-now.com)
- This mechanism was so far assumed to also pertain to the T-cell receptor. (nanotech-now.com)
- The subsequent images collected at the cryo-electron microscope delivered groundbreaking insights into how the T-cell receptor works, as Tamp summarises: On the basis of our structural analysis, we were able to show how the T-cell receptor assembles and recognises antigens and hypothesise how signal transduction is triggered after antigen binding. (nanotech-now.com)
- If these phosphatases are missing, the phosphate groups remain stable at the T-cell receptor and can trigger the next step of the signalling cascade. (nanotech-now.com)
- In addition, it's an important stimulus for employing the T-cell receptor in a therapeutic context for treating infections, cancer, and autoimmune diseases. (nanotech-now.com)

Infection1
- et 20 témoins en bonne santé ne présentant pas d'infection par le virus de l'hépatite C. Une réduction importante de la fréquence des cellules tueuses naturelles totales dans le groupe des patients porteurs d'une infection chronique a été observée par rapport au groupe des témoins ( P = 0,001) ou au groupe des patients dont l'infection a connu une résolution spontanée ( P = 0,01).

Body's1
- Substitutions in both of these positions on the Spike protein have been shown to convey immune escape against human monoclonal antibodies as well as convalescent human sera-meaning these mutations can diminish the body's ability to recognize and respond to the virus 5,6 . (helix.com)
Mutations2
- To facilitate prospective surveillance for such evolution, we map how convalescent serum antibodies are impacted by all mutations to the spike's receptor-binding domain (RBD), the main target of serum neutralizing activity. (biorxiv.org)
- Despite this inter- and intra-person heterogeneity, the mutations that most reduce antibody binding usually occur at just a few sites in the RBD's receptor binding motif. (biorxiv.org)
CONCLUSION1
- CONCLUSION: Patients with spondylarthritis express both HLA-B27 heavy-chain homodimers and receptors for HLA-B27 homodimers. (ox.ac.uk)
