Under conditions where the force of HIV infection per cell is high, partial attenuation of infection with inhibitors can increase the number of live infected cells and may paradoxically be beneficial for viral spread.
To promote longevity under heat stress shares yeast aging factors with progeny through a down-regulation of the diffusion barrier in the membranes between the mitotic cells.
The rapid killing of macrophages by Mycobacterium tuberculosis aggregates, and the subsequent proliferation of the bacteria inside the dead cell, leads to a cell death cascade and explains the coupling of necrosis and pathogen growth observed in active disease.
Developmental cell death plays a key role during insect neurogenesis and is increased in specific neuronal populations in flies that have evolved flightlessness.
Comprehensive scRNA-seq analysis of cardiac stromal cells in healthy and injured hearts reveals novel cell types and non-linear cell dynamics, providing new insights into cardiac inflammation, fibrosis and repair.
The proteins Bax and Bak, which increase the permeability of the mitochondrial membrane during apoptosis, are also crucial for generating a mitochondrial membrane pore that is specifically involved in necrosis.
Novel transgenic zebrafish lines allow selective ablation of neuronal mitochondria by far red light, providing a powerful tool for investigating mitochondrial homeostasis in neurons and mitochondrial mechanisms in neurological disease.
Mouse models in which hypoxia can be genetically triggered in retinal pigmented epithelial cells show that hypoxia-induced metabolic stress alone can lead to photoreceptor atrophy/dysfunction.
