Intrinsic TNFR2 signaling in T regulatory cells provides protection in CNS autoimmunity

2018

Significance In spite of TNF involvement in the pathogenesis of multiple sclerosis (MS), systemic TNF neutralization in MS patients was not successful. One of the possible reasons is that TNF possesses both pathogenic and protective features that may be related to TNFR1 versus TNFR2 receptor engagement. This study uncovers one of such protective functions of TNF mediated by intrinsic TNFR2 signaling in Treg cells. In mice bearing humanized TNF and TNFR2 genetic loci, TNFR2 ablation restricted to Treg cells led to reduced capacity to control Th17 cell responses, exacerbated experimental autoimmune encephalomyelitis (EAE) development, and affected the maintenance of Treg cells. These findings…

Hidden biochemical action of Ethanol on colon carcinoma cell models

Colorectal cancer (CRC) is one of the most widespread cancers in the world. Numerous risk factors have been correlated with the development of CRC, including genetic factors, inflammation, intestinal microflora composition, as well as lifestyle factors, such as smoking, high consumption of red meats and alcohol intake. Epidemiological studies support the conclusion that chronic and heavy alcohol consumption increases the risk to develop CRC as well as favors the progression of this form of cancer. However, the biochemical mechanisms responsible for these events have not yet been fully clarified. The aim of my doctoral project was to study the effects of ethanol in human colorectal carcinoma…
