It is however important in this context to emphasize that the difference we observe is a difference in quantity and kinetics and does not reflect a complete lack of MHC-I presentation as we also find detectable levels of CD8/10.4 T cells in the early phase of infection although at a lower level than CD4/10.4 T cells.
DCs have an alternative pathway for class I presentation known as "cross-presentation", where cell-associated or soluble antigens access and are presented by MHC class I molecules to CD8+ T cells [17].
The B cell response to IFNγ included the induction of genes encoding CD38 and CD69, both of which have been implicated in B cell activation and maturation, and a number of genes involved in MHC class I presentation such as the proteasome subunits (PSMB8 and B9, PSME1 and 2) and TAP1 and 2 transporters.
"I source my own ingredients, I take pride in my mise en place, I care about plating and presentation as much as anybody else," he said.
Our most recent findings that polymorphisms of ERAP1, which encode an endoplasmic reticulum aminopeptidase involved in peptide trimming before HLA class I presentation, only affects AS risk in HLA-B27-positive individuals provides strong evidence that HLA-B27 operates in AS through a mechanism involving aberrant processing of antigenic peptides [ 43].
I'll link to a video of the presentation as soon as I find one, but in the meantime please enjoy these pictures of the screen.
In addition to their tumor targeting capabilities antibodies that mimic the fine specificity of T cell receptors can serve as valuable research reagents that enable to study human class I peptide-MHC ligand-presentation as well as TCR peptide MHC interactions.
Personally, as a member of 85 Broads, I looked forward to hearing her presentation, as I first heard her story at an event in college and she was a speaker that always stood out.
But when advocacy involves a public presentation (which I define as talking in front of three or more people), I panic.
I like to spend as much time and care with the presentation as I do with the baking.
