HIV’s covert methods of evading treatment and immunity

According to Duke Health researchers, the human immunodeficiency virus (HIV) appears to be driven into a latent state, lurking in cells only to erupt once more. This immune response likely evolved to help fight infections.

The primary functions of innate immune cells

An inflammation and a rise in mucus production are typical signs of allergies and worm infections. The innate immune cells are involved in this immunological response, although it is still unclear exactly what they do.

Different cancers carry distinctive genetic signatures

After analyzing data from a public repository, CD4-T, CD8-T cells, and Treg cells, a team of researchers led by bioinformatics Mabel Vidal from the University of Concepcion and working with researchers from MELISA Institute and other academic institutions discovered a distinctive genetic signature among subsets of infiltrating T cells of various types of cancer.

Immunological mechanisms behind the development of alloantibodies

Hemophilia A is the most frequent severe variant of hemophilia. It nearly mostly affects men. The condition is frequently treatable, although not for all patients. A study at the University of Bonn has now highlighted a critical mechanism required for the therapy to be efficient.

Study explains the dynamics underlying liver damage

The immune system may attack the liver when fat builds up there. The chemical that triggers these responses has been discovered by Weill Cornell Medicine researchers in a recent study, and this information helps to explain the dynamics of liver damage that can accompany type 2 diabetes and obesity.
