NBME PATHOLOGY EXAM WITH LATEST VERIFIED QUESTIONS AND 100% CORRECT ANSWERS GRADED A+ Apoptosis: - ANS-Programmed cell death. REQUIRES ATP. Can occur via the intrinsic or extrinsic pathways, both of which involve activation of cytosolic caspases which mediate cellular breakdown. ***Unlike necrosis, apoptosis does not involve significant inflammation. Involves eosinophilic cytoplasm, cell shrinkage, pyknosis and basophilia, membrane blebbing and karyorrhexis, and formation of apoptot...

CLIP correct answer: Remnant of Ii (invariant chain) MIIC Compartments correct answer: Peptide loading compartments for MHC class II Viruses that target MHC antigen processing pathways correct answer: Long-life viruses eg herpes, cytomegalovirus (pulls MHC from ER membrane into cytosol to degrade it) and HIV (enters CD4 cells and destroys them -> body must target own CD4 cells to eliminate it -> HIV can become quiescent and integrate DNA into host DNA to form a provirus) Caspas...
