Secreting cytokines and killing tumor cells can be stressful for a T lymphocyte. In short adverse circumstances, these cells adapt to acute stress. If the situation persists, they activate a chronic stress response mechanism. According to a study by the Institute for Biomedical Research (IRB) in Barcelona, the cytoplasmic polyadenylation element-binding protein 4 (CPEB4) mediated this adaptation process.

Liver damage arrests growth mediated by the somatotroph axis, which prevents liver cell death and inflammation, but increases fibrosis in nonalcoholic fatty liver disease (NAFLD). The explanation for this effect could lie in the relationship between the activating transcription factor 3 (ATF-3) and insulin-like growth factor 1 (IGF-1), according to a study from the University of California at Berkeley.

Researchers led by Emanuel Hanski at the Hebrew University of Jerusalem have identified a class of molecules that inhibit endoplasmic reticulum (ER) stress and could decrease mortality in mice infected with Streptococcus pyogenes, also known as the group A streptococci.
