TXA drug has minimal impact in controlling blood loss in severely injured trauma patients

A recent study found that the drug tranexamic acid has minimal impact in controlling blood loss in severely injured trauma patients at the standard doses given, according to researchers at Washington University School of Medicine in St. Louis.

MIT researchers uncover a possible new way to combat tumors

Under the right circumstances, the body's T cells can detect and destroy cancer cells. However, in most cancer patients, T cells become disarmed once they enter the environment surrounding a tumor.

Study underscores why COVID-19 vaccine boosters are important for all adults

As widely-anticipated decisions about COVID-19 vaccine boosters roll out from U.S. agencies today, insights from an independent study underscore why boosters are important for all adults.

Human lung airway-on-a-chip faithfully recapitulates cystic fibrosis pathology

The inherited progressive disorder cystic fibrosis (CF) causes severe damage to the lungs, and other tissues in the body by affecting the cells that produce mucus, sweat, and digestive juices.

GABA secreted by B-cells blunts the body's cytotoxic T-cell-based response to tumors

A group of scientists led by researchers from the RIKEN Center for Integrative Medical Sciences have discovered that B-cells, a type of immune cell, secrete the neurotransmitter GABA, and also found that the GABA secreted by the B-cells promoted the emergence of anti-inflammatory macrophages, blunting the body's cytotoxic T-cell-based response to tumors.

Can you take the COVID-19 and Influenza vaccines on the same day?

Scientists have conducted a substudy within a phase 3 UK trial and have reported the safety, immunogenicity, and efficacy of the NVX-CoV2373 COVID-19 vaccine when co-administered with licensed seasonal influenza vaccines.

Severe COVID-19 patients have significantly higher NK and T cell frequency

A new study published in the open-access journal Cells aimed to clarify the role of NK and T cell subsets in SARS-CoV-2 infection in hospitalized COVID-19 patients to unravel their potential association with disease severity.

Study reveals mechanism by which vitamin D reduces inflammation caused by immune cells

Scientists recently gained insights into how vitamin D functions to reduce inflammation caused by immune cells that might be relevant to the responses during severe COVID-19. In a study jointly published by Purdue University and the National Institutes of Health, scientists do just that.

New trial demonstrates stable coagulation factor VIII in hemophilia A patients after gene therapy

A novel gene therapy for hemophilia A led to sustained expression of the clotting factor those patients lack, resulting in a reduction – or in some cases complete elimination – of painful and potentially life-threatening bleeding events, according to a new study led by researchers at Children's Hospital of Philadelphia.

SARS-CoV-2 infection and reinfection in farmed mink

A new study finds that farmed mink acquire SARS-CoV-2 infection, freely transmit it among themselves, and were reinfected, despite being seropositive.

Short-term severe calorie restriction safe, feasible, and well tolerated by cancer patients

A diet involving short-term, severe calorie restriction was safe, feasible, and resulted in a decrease of blood glucose and growth factor concentration, reduction in peripheral blood immunosuppressive cells, and enhanced intratumor T-cell infiltration in cancer patients receiving standard-of-care therapy, according to the results of a clinical trial.
