Two HIV vaccine trials show proof of concept for pathway to broadly neutralizing antibodies
A new study combining data from two separate phase 1 clinical trials shows that a targeted vaccine strategy can successfully activate early immune responses relevant to HIV, and, in one trial, further advance them.

Scientists find two brain biomarkers in long COVID sufferers may be what’s causing brain fog
A new study that compares inflammation and brain stress responses in long COVID-19 patients with individuals who have fully recovered shows those with cognitive issues have a lower ability to adapt to stress and higher levels of inflammation in their brains.

Researchers reveal lipid-based communication between body and gut microbes
A new study shows how a host protein can specifically recognize bacterial lipids, thus triggering beneficial immune responses. It also highlights a new way the body actively shapes the gut microbiome by communicating with microbes to maintain balance.

New study reveals our skin’s own bacteria can help protect us from the bad effects of sunlight
Researchers have substantiated that certain skin bacteria can protect us from the sun’s ultraviolet (UV) radiation specifically by metabolizing cis-urocanic acid using an enzyme called urocanase. This enables the skin’s ability to fine-tune how it responds to UV radiation.

‘Loop’hole: HIV-1 hijacks human immune cells using circular RNAs
In a groundbreaking discovery, researchers have identified a never-before-seen mechanism that enables the human immunodeficiency type 1 virus (HIV-1) to evade the body’s natural defenses and use it to support its survival and replication.

To restore gut health, a healthy diet outperforms fecal transplants
When our microbial ranks are damaged or depleted — whether by inflammatory bowel diseases, antibiotic regimens or bone marrow transplants — it is crucial to restore them. According to a new study, the most effective way of rebuilding the microbiome is also the simplest: maintaining a healthy diet.

Scientists reveal key bacterial immune mechanism
Researchers have uncovered a pivotal mechanism by which bacteria defend themselves against viral infection. Cyclic dinucleotides (CDNs), synthesized during activation of the cyclic oligonucleotide-based anti-phage signaling system (CBASS) immune mechanism, trigger the filamentous assembly of phospholipase effectors, which execute the downstream immune response.

New study offers insights into designing safe, effective nasal vaccines
Researchers found that nasal vaccine boosters can trigger strong immune defenses in the respiratory tract, even without the help of immune-boosting ingredients known as adjuvants. The findings, researchers suggest, may offer critical insights into developing safer, more effective nasal vaccines in the future.

Chimpanzees use medicinal leaves to clean and treat their wounds
Scientists studying chimpanzees in Budongo Forest, Uganda, have observed that these primates don’t just treat their own injuries, but care for others, too — information which could shed light on how our ancestors first began treating wounds and using medicines.
