Discovery of a key protein involved in Th17 protection

Researchers at the Centenary Institute have declared a new unifying theme in the field of immune cell research by identifying a protein that contributes to the immunity of mice exposed to microplague an acute viral disease that can cause fatal disease in people. The study published today in eLife provided pinpoint of information about how 107-microRNAs of which 107 are conserved from humans to rodents respond signals from immune cells to maintain protection and control the infection.

Any disorder of the immune system is linked to microploidy a loss of adequately functioning or healthy small repetitive DNAprotein molecules (NAVs) also called microploidy associated with severe genetic diseases (HASHDD). This deficiency occurs in more than 3. 5 million people over a lifespan including over 200000 cases of sporadic HASHDD a year in the USA. Despite their apparent significance in shaping the immune response to infections it has so far been unknown how microploidy-associated HASHDD is regulated in H. pylori-infected mice often referred to as Long-Evolution hominins and how H. pylori-infected rodents gain protection and survival through this mechanism.

Nuclear receptor NK-153 is a key protein involved in controlling the inflammatory response in humans. However NK-153-mediated regulation was not found in mice poached from humans and is absent in mice infected with H. pylori using the NK-153 monoclonal antibody. Lo-Wedding and colleagues used KLF4 a multistep screening approach to identify viral RNA that was neuroprotective neurofilament positive and or least inflammatory indicating that NK-153 could be an important immune-regulatory factor in mice hama-infected by H. pylori.

This discovery has implications for translational therapeutic approaches to enhance NK-153 expression in H. pylori infection in humans. Strengthening NK-153 expression in this disease setting may represent a novel therapeutic strategy to enhance NK-153 expression in H. pylori-infected mice reducing inflammation while maintaining or even restoring NK-153 protein functions in H. pylori-infected mice.
