A lipid mediator lysophosphatidic acid (LPA) derived from fibroblastic reticular cells regulates T-cell movement through the densely packed reticular network in lymph nodes in a manner dependent on the LPA receptor LPA2-ROCK-myosin II.
L. interrogans utilizes endocytic recycling and vesicular transport systems for transcytosis across endothelial or epithelial barrier in blood vessels or renal tubules, which contributes to spreading and transmission of leptospirosis.
Analysis of neurons that lack the two neuronal dynamins, dynamin 1 and 3, demonstrates a pathway of synaptic vesicle reformation that does not require these two dynamins or clathrin-dependent budding.
A generally applicable two-hybrid assay demonstrates that MHC class I heavy chains devoid of beta-2 microglobulin associate within and across allotypes, with implications for endocytosis and autoimmunity.
Impaired lysosomal acidification results in retention of iron inside lysosomes, triggering functional iron deficiency, dysfunctional mitochondria (especially mtDNA loss), and inflammation in vivo in a mouse model of lysosomal disease.
Targeting senescent cells in human intervertebral discs, using senotherapeutics, provides a potential therapeutic strategy to prevent or reduce disc degeneration and pain.
