Optimisation of a screening platform for determining IL-6 inflammatory signalling in the senescence-associated secretory phenotype (SASP).

abstract：:Lung injuries are generally more serious and cause high mortality in aged humans and animals. Heme oxygenase-1 (HO-1) is known to be readily inducible in alveolar macrophages (AMs) and airway epithelial cells to confer cytoprotection against oxidative stress. We thus investigated whether aging impairs the stress-induc...
