Bidirectional MHC molecule exchange between migratory and resident dendritic cells.

abstract：:The immune system is armed with a broad range of receptors to detect and initiate the elimination of bacterial pathogens. Inflammasomes are molecular platforms that sense a diverse range of microbial insults to develop appropriate host response. In that context, noncanonical inflammasome arose as a sensor for Gram-neg...

Disease-associated inflammation is one mechanism thought to fuel this pathogenic feed-forward loop. Several lines of evidence indicate that proinflammatory B cells promote T2D and PD; thus, B cells are top candidat...
