The principal microtubule-organizing center in animal cells, the centrosome, contains centrin, a small, conserved calcium-binding protein unique to eukaryotes. Several centrin isoforms exist and have been implicated in various cellular processes including nuclear export and deoxyribonucleic acid (DNA) repair. Although...

Oxidative stress and Th17 cytokines are important mediators of inflammation. Treatment with beta-adrenoceptor (ADRB) antagonists (beta-blockers) is associated with induction or aggravation of psoriasis-like skin inflammation, yet the underlying mechanisms are poorly understood. Herein, we identify lysosomotropic beta-blockers as critical...
