Study uncovers key mechanism behind HIV latency

An immune response that likely evolved to help fight infections appears to be the mechanism that drives human immunodeficiency virus (HIV) into a latent state, lurking in cells only to erupt anew, researchers at Duke Health report.

MEMPHIS system sheds light on vaccine response differences across ages

mRNA vaccines saved lives during the COVID-19 pandemic, but older people had less of an immune response to the vaccines than did younger adults. Why? Boston Children's researchers, led by Byron Brook, PhD, and Ofer Levy, MD, PhD, have found some answers, while providing proof-of-concept of a new system that can model vaccine responses in a dish.

New biomarker could predict response to IBD treatment

Not everyone responds equally well to treatments for inflammatory bowel disease (IBD). What will work for individual patients involves trial and error during the treatment process.

Elevated antibody responses to Epstein-Barr virus linked to increased risk of multiple sclerosis

Researchers identified a unique antibody signature against the Epstein-Barr virus protein EBNA1 that correlates with cross-reactive immune responses in multiple sclerosis (MS) patients. This connection provides new insights into how EBV infection may drive MS pathogenesis.

Research uncovers intrinsic factors influencing CAR-T cell success

Researchers from the Josep Carreras Leukaemia Research Institute have found that the efficacy of varni-cel, a CAR-T infusion product for B-ALL patients, is highly dependent on intrinsic features of the CAR-T cells themselves and their progression within the patient.

Discovery of stem-like CD4 T cells offers new hope for cancer immunotherapy

Researchers at Winship Cancer Institute of Emory University have identified a novel type of immune cell, called the stem-like CD4 T cell, that plays a pivotal role in anti-tumor immunity.

Caloric restriction extends mouse lifespan and health in new genetic study

Study examined the effects of caloric restriction (CR) and intermittent fasting (IF) on the health and lifespan of genetically diverse female mice, revealing that CR extended lifespan more significantly than IF. Genetic factors also played a role in how dietary restriction influenced aging and health.

Sweden exceeds UNAIDS HIV goals but faces new challenges

Sweden has surpassed the UNAIDS 95-95-95 targets, with reduced HIV incidence and a steady increase in diagnosed and treated cases. However, challenges remain, especially among migrant populations and recent arrivals.

Researchers uncover the potential of JAK inhibitors to treat life-threatening skin disease

Researchers identified Janus kinase inhibitors as a promising treatment for the severe drug-induced skin condition toxic epidermal necrolysis, by analyzing patient biopsies with deep visual proteomics.

Dual immunotherapy plus chemotherapy shows promise for specific lung cancer patients

Researchers from The University of Texas MD Anderson Cancer Center have demonstrated that patients with metastatic non-squamous non-small cell lung cancer (NSCLC) harboring specific mutations in the STK11 and/or KEAP1 tumor suppressor genes were more likely to benefit from adding the immunotherapy tremelimumab to a combination of durvalumab plus chemotherapy to overcome treatment resistance typically seen in this patient population.

Researchers gain new understanding of how immune cells respond to heat during fever

The study reveals that moderate fever enhances CD4 T cell activity while reducing regulatory T cell suppression, highlighting temperature's immune effects.

Dietary antigens reduce small intestine cancer by boosting immune T-cells

Study shows that dietary antigens can suppress small intestine carcinogenesis by activating T-cells through Peyer's patches. Adding bovine serum albumin (BSA) or ovalbumin (OVA) to antigen-free diets restored immune function and reduced tumor growth in mice.

Long COVID patients maintain robust immune memory two years after infection

Researchers discovered that SARS-CoV-2-specific T and B cells in long COVID patients are maintained for two years, similar to fully recovered individuals, offering insights into long-term immunity.

Tossed medicine, delayed housing: How homeless sweeps are thwarting Medicaid’s goals

Andrew Douglass shoved his clothes and belongings into plastic trash bags as five police officers surrounded his encampment — a drab gray tent overflowing along a bustling sidewalk in the gritty Tenderloin neighborhood, where homeless people lie sprawled on public sidewalks, sometimes in drug overdoses.
