Chelico's lab studies immune responses to HIV, particularly a family of proteins called APOBEC3 which cause mutations in the HIV virus. Her research and others' show that the virus uses a ...

Antibodies are best known for their ability to latch onto and neutralize bacteria, viruses and other pathogens. But these ...

Lipids are the fatty molecules that make up cellular membranes, creating a protective barrier that regulates what enters and ...

3) Protein binds to HIV fragment on helper T cell and CD3 receptor on killer T cell, activating the killer T cell and bringing the two cells close together. 4) Activated killer T cell destroys HIV ...

described a bispecific antibody-like protein that attacks those reservoirs by coaxing HIV out of hiding and targeting infected cells for destruction. “In order to kill the [infected] cell, the cell ...

HIV tests are based on the detection of antibodies to HIV. These are proteins produced by the immune system in response to a foreign substance, such as HIV. The main cause of false positive results is ...

"If you have a negative result on a highly sensitive test, you can rule out HIV." A protein substance (immunoglobulin) produced by the immune system in response to a foreign organism. Many diagnostic ...

HIV infects cells by attaching to a protein on their surface, called CCR5. Some people have a genetic mutation that changes the shape of this protein, meaning HIV can no longer attach to their ...

When we know the structure of a protein, we can attempt to design small drug molecules to bind to it and block its function. The power of this approach has been shown in the battle against HIV and ...

a new study published in Cell Reports on November 22 finds that a protein produced by HIV called Nef can cause long-lasting chronic inflammation in a mouse model of HIV—and that the inflammation may ...

June 17, 2020 — To defend the body, the immune system makes proteins known as antibodies that latch onto the perceived threat, be it HIV, the new coronavirus or, as is the case in autoimmune ...

Understanding how ... A Chain Reaction: HIV Vaccines Can Lead to Antibodies Against Antibodies Jan. 17, 2025 — Many vaccines work by introducing a protein to the body that resembles part of a virus.
