In human male-female pairs with a less similar suite of genes for human leukocyte antigens, sperm fare better when exposed to cervical mucus.

Researchers find that it’s not just high-risk genes, but how children’s bodies respond to their own intestinal microbiota that relates to future diagnoses of type 1 diabetes.

Matching the immunological characteristics of donor retinal cells to those of the recipient can reduce the chance of rejection.

People can be identified by the distinctive ways they perceive odors, a new study shows.

An HIV drug can bind to and alter the function of an immune molecule, causing a dangerous reaction in patients with a particular allele.

Modern immune systems harbor signs of interbreeding with ancient hominins.

It may be time to reconsider an AIDS vaccine which is more human than viral, triggering the immune system in a way that no other vaccine does.
