Researchers have found that optimizing the energy metabolism of CD4 lymphocytes enables people with HIV-1 to better defend themselves against the virus.

Researchers have identified a major source of how mu-opioids mediate reward. It could be possible to create safer opioids by bypassing the part of the brain that feels pleasure while retaining analgesic properties.

A new study published in Science generated data on thousands of proteins circulating in our blood and combined this with genetic data to produce a map showing how genetic differences that affect these proteins link together seemingly diverse as well as related diseases.

The extract of the plant Corydalis yanhusuo prevents morphine tolerance and dependence while also reversing opiate addiction, according to a recent study led by the University of California, Irvine.

A study shows that regular doses of oxytocin do not appear to overcome deficits in social functioning among children with autism spectrum disorder.

Research finds that poor timing of influenza vaccination campaigns in a region of Brazil led to an increase in premature births, lower birth-weight babies and the need to deliver more babies by cesarean section.

Natural peptides bind GABA receptors and have anti-anxiety and sleep-enhancing effects. For example, treating a protein in cow’s milk, called casein, with the digestive enzyme trypsin produces the mixture of sleep-enhancing peptides known as CTH. Scientists wanted to know if they could find other, perhaps more powerful sleep-enhancing peptides.

Scientists at Washington University School of Medicine in St. Louis have developed a chemical compound that interferes with a key feature of many viruses that allows the viruses to invade human cells.

Research finds that both the Pfizer and Moderna vaccines lead to the generation of long-term populations of T cells that can recognize multiple variants of the SARS-CoV-2 virus.

Scientists have discovered a highly potent monoclonal antibody that targets the SARS-CoV-2 spike protein and is effective at neutralizing all variants of concern identified to date.
