Thanks to the marine worm Platynereis dumerilii, an animal whose genes have evolved very slowly, scientists from CNRS, Université de Paris and Sorbonne Université, in association with others at the University of Saint Petersburg and the University of Rio de Janeiro, have shown that while haemoglobin appeared independently in several species, it actually descends from a single gene transmitted to all by their last common ancestor.

In some cases, immune cells in the lungs can contribute to worsening a virus attack. In a new study, researchers describe how different kinds of immune cells, called macrophages, develop in the lungs and which of them may be behind severe lung diseases.

The Global T cell Expert Consortium (GTEC) has been officially established to focus on maximizing the use and direction of T-cell research in the global battle against COVID-19 and other infectious diseases.

Researchers have found a way to identify sequences of Viruses that had not before been looked at in great detail.

Researchers have uncovered the evolutionary journey of Salmonella species over 50 years, and they may have discovered a new lineage along the way.

New developments in cellular imaging have resulted in a new method being created that allows for observation of T-cell binding and activation of immune defenses.

In urban environments, allergic diseases are more common among dogs and their owners compared to those living in rural areas. Simultaneous allergic traits appear to be associated with the microbes found in the environment and consequently on skin, but gut microbes differ between dogs and humans.

A new gene has been discovered which can allow for cells to engulf and destroy invading viruses effectively.

New research has determined how the enzymes controlling T and B cell development are able to make the decision of which class to differentiate them into.

Scientists have developed a promising new approach for treating lymphomas, cancers that begin in infection-fighting cells of the immune system called lymphocytes.
