The NLRP3 inflammasome is a multi-protein complex that drives sterile and pathogen-dependent inflammation. Activation of the NLRP3 inflammasome occurs in two steps: priming and activation. Priming occurs in response to an inflammatory stimulus, such as LPS. LPS-primed macrophages are subsequently activated by a second stimuli, most of which require K+...
One of the fundamental observations in oncology is that the rate of cancer malignancy increases with age, which applies to most human malignancies including breast cancer. Therefore, it is crucial to elucidate the mechanistic connection between aging and carcinogenesis. The NAD+-dependent sirtuin family, specifically SIRT3, the primary mitochondrial deacetylase, which...
Inter-organelle contacts facilitate communication between organelles and impact fundamental cellular functions. Investigations into the molecular mechanisms of inter-organelle tethering are still in the early stages, and we are just beginning to appreciate the number and variety of inter-organelle tethers that exist. We have used budding yeast as a model polarized...
