Identifying the drivers of the observed interindividual variability of the human immune system is crucial to our understanding of infectious and immune-mediated diseases. The contribution of genetic and non-genetic factors to immunological differences betw ...
Long-term intracellular symbiosis (or endosymbiosis) is widely distributed across invertebrates and is recognized as a major driving force in evolution. However, the maintenance of immune homeostasis in organisms chronically infected with mutualistic bacte ...
The use of adult Drosophila melanogaster as a model for hematopoiesis or organismal immunity has been debated. Addressing this question, we identify an extensive reservoir of blood cells (hemocytes) at the respiratory epithelia (tracheal air sacs) of the t ...
The mammalian cyclic dinucleotide 2', 3'-cGAMP is a potent inducer of innate immune responses produced upon detection of cytosolic DNA by cGAS. The mechanisms underlying the control of intracellular cGAMP levels remained unclear. In a new study, Eaglesham ...
Mitochondria have emerged as key actors of innate and adaptive immunity. Mitophagy has a pivotal role in cell homeostasis, but its contribution to macrophage functions and host defense remains to be delineated. Here, we showed that lipopolysaccharide (LPS) ...
Insects commonly harbor facultative bacterial endosymbionts, such as Wolbachia and Spiroplasma species, that are vertically transmitted from mothers to their offspring. These endosymbiontic bacteria increase their propagation by manipulating host reproduct ...
Tuberculosis (TB) is caused by infection with Mycobacterium tuberculosis (Mtb) and represents one of the most relevant bacterial diseases worldwide. Recent advances have yielded new insights into the molecular basis of the immune response required for rest ...
In many animals, females respond to mating with changes in physiology and behavior that are triggered by molecules transferred by males during mating. In Drosophila melanogaster, proteins in the seminal fluid are responsible for important female postmating ...
Much has been learned about the genetics of aging from studies in model organisms, but still little is known about naturally occurring alleles that contribute to variation in longevity. For example, analysis of mutants and transgenes has identified insulin ...
The lymphatic system serves a critical role in fluid homeostasis, lipid metabolism and immune surveillance. The growing appreciation of its implication in various diseases challenges the conventional view of lymphatics as a passive transport system. Tradit ...
