Antigen presentation by platelet extracellular vesicles, fibril-reactive monoclonal antibody therapy for AL amyloidosis, and targeting gasdermin D in sepsis

In this week’s episode, we’ll review a research article demonstrating that some platelet-derived extracellular vesicles harbor proteasomes that can process and present antigens via MHC class I molecules. Next, we’ll review results of a phase 1 study of a fibril-reactive monoclonal antibody that was well tolerated and led to rapid, sustained organ responses in patients with AL amyloidosis. We’ll close with a research article suggesting that the pore-forming protein gasdermin D, which plays a crucial role in the release of neutrophil extracellular traps, is a promising drug target in sepsis.
