Study identifies a protein complex critical for regulating apoptosis and necroptosis

Cell death plays an important role in normal human development and health but requires tightly orchestrated balance to avert disease. Too much can trigger a massive inflammatory immune response that damages tissues and organs. Not enough can interfere with the body's ability to fight infection or lead to cancer.

Research provides a stronger connection between autoantibody formation and clotting in COVID-19

Scientists have discovered that "rogue" antibodies found circulating in the blood of COVID-19 patients have the potential to cause cells to lose their resistance to clotting.

New finding may aid in development of vaccines against future animal-to-human viral diseases

A future vaccine providing protection against a wide range of coronaviruses that jump from their original animal hosts to humans -; including SARS-CoV-2, the cause of COVID-19 -; may be possible, say Johns Hopkins Medicine researchers, based on findings from their recent study.

Study shows link between oral microbiome and naturally occurring alveolar bone loss

It is becoming increasingly clear that the human microbiome – the collection of bacteria, viruses and fungi that live on and within us – significantly contributes to our health.

ChAdOx1 vaccine found to protect Syrian hamsters against SARS-CoV-2 variants

Researchers recently evaluated the efficacy of the Oxford ChAdOx1 (AZD 1222/ AZD2816) vaccine against the Omicron, Delta, and Beta variants of SARS-CoV-2 in Syrian hamsters.

Vaccination likely to be more protective against SARS-CoV-2 viral variants than natural infection

Antibodies generated by COVID-19 vaccines are more suited to recognizing viral variants than antibodies that arise from natural infection, according to a study by researchers at Stanford Medicine.

Study shows how some cancer cells immobilize T cells

Our immune systems have the potential to find and destroy cancer cells. But cancer cells can be clever and develop tricks to evade the immune system.

Twin study identifies the influence of environment and genetics in multiple sclerosis

Researchers at the University of Zurich and Munich's LMU Klinikum hospital have studied the immune system of pairs of monozygotic twins to identify the influence of the environment and of genetics in cases of multiple sclerosis.

Antibodies become more powerful for at least six months after COVID-19 vaccination

For at least six months after COVID-19 vaccination, antibodies produced by immune cells become steadily more formidable and more precisely targeted against the virus that causes COVID-19, according to a study of the antibody response to the Pfizer-BioNTech vaccine by researchers at Washington University School of Medicine in St. Louis.

New cholera vaccine generates long-lasting antibody responses in mice

Cholera, a diarrheal disease caused by the highly transmissible bacteria Vibrio cholerae, kills tens of thousands of people each year worldwide.

The long-term consequences of SARS-CoV-2 infection in people with HIV

In a recent study posted to the medRxiv* preprint server, an interdisciplinary team of researchers from the United States (US) analyzed a cohort of patients with human immunodeficiency virus (HIV) (PWH) recovering from coronavirus disease 2019 (COVID-19) and characterized severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific immune responses in these patients.

New approach to alter the skin microbiome and reduce acne lesions using bacteria

Acne on the face is often treated with topical antibiotics, which tend to be used for an extended period of time and contribute to the serious problem of antibiotic resistance.

Researchers find potential new strategy to treat metastatic form of intra-abdominal cancer

Researchers from the National Cancer Centre Singapore (NCCS) have found a potential new strategy to treat peritoneal carcinomatosis, a metastatic form of intra-abdominal cancer, where patients are presented with limited treatment options and poor overall survival.

A third known case of HIV remission involving stem cell transplant documented

A woman with HIV who received a cord blood stem cell transplant to treat acute myeloid leukemia has had no detectable levels of HIV for 14 months despite cessation of antiretroviral therapy (ART), according to a presentation at today's Conference on Retroviruses and Opportunistic Infections (CROI).
