NewsStudy maps how tuberculosis bacteria power themselves
A new study provides the first detailed 3D structure of a protein called EtfD, which the bacterium Mycobacterium tuberculosis uses to extract energy from lipids (fats), along with the first laboratory test capable of directly measuring its activity.

NewsHow one flu virus can hamper the immune response to another
Prior exposure to one strain of influenza virus may weaken children’s ability to mount an effective antibody response against their subsequent exposure to a different flu strain, according to a study.

NewsNew strategies aim at HIV’s last strongholds
A new study has overcome a long-standing challenge—how to isolate and study elusive HIV-infected cells called authentic reservoir clones (ARCs) that evade the immune system, making the disease difficult to cure.
-
NewsHow food shortages reprogram the immune system’s response to infection
When food is scarce, stress hormones direct the immune system to operate in “low power” mode to preserve immune function while conserving energy. This reconfiguration is crucial to combating infections amid food insecurity.

NewsGut bacteria may tip the balance between feeding tumors and fueling immunity
A new study reveals how bacteria in the gut can help determine whether the amino acid asparagine from the diet will feed tumor growth or activate immune cells against the cancer.

NewsNIH grant aims for childhood vaccine against HIV
A multi-institutional team led by Weill Cornell Medicine investigators has been awarded a five-year, $20.8 million grant from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, for advanced preclinical development of a promising experimental HIV vaccine.

NewsNew ‘cough simulator’ mimics TB transmission with unprecedented accuracy
Researchers have developed a new experimental system called Transmission Simulation System (TSS) that replicates the airborne transmission of TB – by simulating the human cough – with unparalleled realism and never-before-seen precision.

NewsMERIT grant awarded to study cure for HIV
A scientific team has received an NIH MERIT Award to provide long-term grant support to study a handful of people who have managed to clear HIV after a stem cell transplant and those who did not.

NewsNovel immunologic surveillance study provides new insights into post-pandemic return of respiratory viruses
Non-pharmaceutical interventions such as masking and distancing targeted towards SARS-CoV-2 during the pandemic also decreased circulation rates of and population immunity to common respiratory pathogens in children, a new study shows.
-
NewsImmune tolerance to gut microbes is initiated by a key bacterial sensor
A study has found that the body’s immune “tolerance” to gut microbes depends on an ancient bacterial-sensing protein called STING—normally considered a trigger for inflammation.

NewsNovel molecular maneuver helps malaria parasite dodge the immune system
Researchers have discovered how a parasite that causes malaria when transmitted through a mosquito bite can hide from the body’s immune system. Plasmodium falciparum can shut down a key set of genes, rendering itself “immunologically invisible.”
-
NewsNew CDC nPEP Guidelines should become ‘part of general medical practice’
Health experts say the updated CDC HIV Non-Occupational Post Exposure Prophylaxis (nPEP) Guidelines should be part of general medical practice, as incorporating them will reduce new HIV infections and improve public health.

NewsDr. Sabine Ehrt named Chair of the Department of Microbiology and Immunology at Weill Cornell Medicine
Dr. Sabine Ehrt, an internationally renowned leader in tuberculosis research, has been appointed chair of the Department of Microbiology and Immunology at Weill Cornell Medicine.

NewsGut microbes release cancer-fighting bile acids that block hormone signals
Bacteria naturally present in the human intestine can transform cholesterol-derived bile acids into powerful metabolites that strengthen anti-cancer immunity by blocking androgen signaling, according to a preclinical study.

NewsMicrobes in Brooklyn Superfund site teach lessons on fighting industrial pollution
Researchers discover unprecedented pollution-fighting genetic adaptations in tiny organisms inhabiting Brooklyn’s highly contaminated Gowanus Canal, revealing a potential new approach for cleaning contaminated waters and recovering valuable resources.
-
NewsParasitic infection and treatment linked to cancer-related gene activity in the cervix
New research has revealed that Schistosoma haematobium, a parasitic infection affecting millions globally, can trigger cancer-related gene activity in the cervical lining, with changes becoming even more pronounced after treatment.
-
NewsStudy finds new targets needed for vaccine to prevent herpesvirus transmission to babies
Despite the lack of research on vaccines against congenital cytomegalovirus (CMV), a research has recently discovered that the virus is able to cause cross-placental transmission even with the absence of multple essential proteins, providing insights for future vaccine development.
-
NewsStudy discovers tuberculosis genes necessary for airborne transmission
Tuberculosis bacteria rely on a family of genes that help them survive the challenging journey from one person’s lungs to another person’s during coughing, sneezing or talking, according to a study that offers new targets for tuberculosis therapies.
-
NewsDesigning self-destructing bacteria to make effective tuberculosis vaccines
Preclinical studies have demonstrated a more effective tuberculosis (TB) vaccine through engineering bacteria to self-destruct and swiftly stops the infection on cue, which activates a more robust immune response.

NewsDigging into a decades-old hepatitis B mystery suggests a new potential treatment
In their effort to answer a decades-old biological question about how the hepatitis B virus (HBV) is able to establish infection of liver cells, researchers have identified a vulnerability that opens the door to new treatments.
