A chromatin boundary factor that is only active during early embryo development has been discovered in Drosophila.

A combination of advanced optical imaging and cryogenic electron microscopy has been used to explore membrane fusion in a synthetic system and provide new insights into neurotransmitter release.

Mathematical modeling shows that local populations of the malaria parasite self-organize into a limited number of transient but distinct strains through competition for hosts in immunity space.

Experiments in mice have shown than an enzyme that repairs broken DNA inside the nucleus also has a central role in the innate immune system because it is able to detect foreign DNA outside the nucleus.

By using immune cells called dendritic cells to deliver drugs, it is possible to target and kill specific members of another class of immune cell, known as T cells, and to prevent these cells from attacking the body's own tissues in cases of autoimmune disease.

Long-lived intermediate states formed by glycoprotein catalysts are an essential part of the process used by influenza virus particles to infect cells.

Some of the mutations that occur during influenza evolution can only be tolerated in conjunction with other mutations that increase the stability of a viral protein.

By comparing gene expression in people before and after they received the influenza vaccine, researchers were able to identify genes that contribute to differences in individual responses to vaccination.
