The maintenance of oocytes in the mammalian ovary involves extreme protein longevity

Nature Cell Biology, Published online: 20 June 2024; doi:10.1038/s41556-024-01442-7Harasimov, Gorry, Welp, Penir, Horokhovskyi et al. analyse proteostasis in mammalian oocytes and ovaries: the maintenance of oocytes involves exceptional protein longevity, and many of the extremely long-lived proteins decline as the ovary ages.

Mitochondria and cell death

Nature Cell Biology, Published online: 20 June 2024; doi:10.1038/s41556-024-01429-4Several processes of regulated cell death engage or use mitochondria, which are thus central hubs that not only coordinate cell death but also elicit non-lethal signalling mediated by mitochondrial outer membrane permeabilization.

CD63 sorts cholesterol into endosomes for storage and distribution via exosomes

Nature Cell Biology, Published online: 17 June 2024; doi:10.1038/s41556-024-01432-9Palmulli, Couty and colleagues show that the tetraspanin CD63 promotes accumulation of cholesterol in intraluminal vesicles (ILVs) at the expense of retrieval from endosomes; cholesterol stored in ILVs and exosomes is recovered in an NPC1-dependent manner.
