Daily statin medication could improve cardiovascular outcomes in people with HIV

A National Institutes of Health clinical trial was stopped early because a daily statin medication was found to reduce the increased risk of cardiovascular disease among people living with HIV in the first large-scale clinical study to test a primary cardiovascular prevention strategy in this population.

New therapeutic approach to eliminate aging cells by boosting anti-viral immune response

Aging, or senescent cells, which stop dividing but don't die, can accumulate in the body over the years and fuel chronic inflammation that contributes to conditions such as cancer and degenerative disorders.

The breadth of immune responses following COVID-19 vaccination in hematology patients with diseases and treatments impacting B cell immunity

A study published in Cell Reports Medicine describes that COVID-19 vaccines induce strong T cell response in blood cancer patients, irrespective of antibody response and B cell numbers.

Diverse subset of T-cell clones plays a role in the antitumor effects of immune checkpoint inhibitors

Immune checkpoint inhibitors (ICIs) are widely sought after for the treatment of different types of cancers. Unfortunately, only 20–30% patients with cancer respond to ICI treatment.

Myeloid cells can harbor HIV in people taking antiretroviral therapy

A subset of white blood cells, known as myeloid cells, can harbor HIV in people who have been virally suppressed for years on antiretroviral therapy, according to findings from a small study supported by the National Institutes of Health.

Monocytes may be a stable reservoir of HIV in patients taking antiretroviral therapy

To develop treatments that may one day entirely rid the body of HIV infection, scientists have long sought to identify all of the places that the virus can hide its genetic code.

UW researchers identify a target that may make bone marrow transplants safer and more effective

A bone marrow transplant can be a lifesaving treatment for people with relapsed blood cancers, but a potentially lethal complication known as graft-versus-host disease put limitations on this procedure.

SARS-CoV-2 infection damages CD8+ T cell response

In a recent study published in the journal Immunity, a team of researchers from the United States found that previous severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections reduce the activation and expansion of CD8+ T cells in response to coronavirus disease 2019 (COVID-19) vaccinations.

Tetravalent COVID vaccine provides broad antibody responses against SARS-CoV-2 variants in animal model

In a recent study posted to the bioRxiv* preprint server, researchers in Italy and the United States evaluated the efficacy and immunogenicity of an adjuvanted tetravalent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike (S) protein subunit 1 (S1) COVID-19 vaccine.

SARS-CoV-2 infection damages the CD8+ T cell response to vaccination

The magnitude and quality of a key immune cell's response to vaccination with two doses of the Pfizer-BioNTech COVID-19 vaccine were considerably lower in people with prior SARS-CoV-2 infection compared to people without prior infection, a study has found.
