Before their exposition on the cell surface, the MHC class II molecules react with endocytosed exogenous antigens, which are then presented to the T cells. The antigen-binding grove between MHC class II alpha and beta chain is open at both ends and is 15-24 amino...

Why areMHC class II–restricted responses usually not considered in tumor development? One reason could be that most tumors do not express MHC class II molecules. Exceptions are—obviously—B cell leukemias like chronic lymphocytic leukemia, Burkitt lymphoma, EBV-induced B cell non-Hodgkin lymphoma,...
The presentation of peptide-MHCII complexes (pMHCIIs) for surveillance by T cells is a well-known immunological concept in vertebrates, yet the conformational dynamics of antigen exchange remain elusive. By combining NMR-detected H/D exchange with Markov modelling analysis of an aggregate of 275 mi...
The high levels of polymorphism at MHC class II loci found in most vertebrate species are thought to be maintained by different forms of balancing selection, including hetero- zygosity advantage (Doherty and Zinkernagel, 1975) and rare allele advantage (also called negative frequency- dependent ...
For example, SARS-CoV-2 ORF6 blocks type II interferon-mediated immune responses and promote viral infection and replication [27]. In addition, angiotensin-converting enzyme 2 (ACE2) or major histocompatibility complex (MHC) alleles are associated with viral titers [20, 28]. MHC molecules are ...
MHC class I molecules are ubiquitously expressed while MHC class II molecules are expressed in specialized Antigen Presenting Cells (APCs) like dendritic cells, B cells and macrophages and in several cell types under inflamed conditions. Therefore, it is unlikely that MHC class I is expressed by ...
