Turning back the clock on aging immune systems: New treatment rejuvenates elderly defenses

Study demonstrated that selectively reducing myeloid-biased hematopoietic stem cells (my-HSCs) in aged mice rejuvenated the immune system, enhanced lymphopoiesis, reduced inflammation, and improved responses to viral infection, highlighting a potential strategy for countering age-related immune decline.

Females' immune system edges out males but at a cost of higher autoimmune risk

A review article highlights how two X chromosomes in females influence immune system composition and function, leading to faster infection clearance and stronger vaccination responses but also a higher risk of autoimmune diseases.

New mechanism discovered: B cells' contribution to immune tolerance in thymus gland

Immune cells must learn not to attack the body itself. A team of researchers from the Technical University of Munich (TUM) and the Ludwig Maximilian University of Munich (LMU) has discovered a previously unknown mechanism behind this: other immune cells, the B cells, contribute to the "training" of the T cells in the thymus gland.

New study reveals key tissues involved in HIV rebound after treatment

In findings that have implications for potential new HIV therapies, researchers from Texas Biomedical Research Institute (Texas Biomed) used genetic sequencing techniques on the nonhuman primate version of the virus to identify that lymph nodes in the abdomen are the leading source of rebound infection after the first week of stopping antiretroviral treatment.

Study reveals intestinal helminth infection diminishes T cell response to COVID-19 mRNA vaccine

Study investigates the impact of helminth infection on COVID-19 mRNA vaccine efficacy, revealing that while antibody responses remain largely unaffected, T-cell responses are significantly impaired, particularly against Omicron variants.

New approach using ultrasound-guided drug delivery effectively targets lymph node metastasis

Researchers at Tohoku University have discovered a new approach for treating lymph node metastasis. Anticancer drugs are administered directly into the LNs under ultrasound guidance (Lymphatic Drug Delivery System or LDDS) to target sentinel lymph nodes (LNs) and generate antitumor effects locally, preventing distant metastasis.

New combination treatment offers hope for older patients with mantle cell lymphoma

The phase 2 trial PrE0405 met its primary endpoint, achieving a complete response (CR) rate of 85% in 33 patients over the age of 60 with mantle cell lymphoma (MCL) who received bendamustine and rituximab, a standard chemo-immunotherapy treatment, along with venetoclax, which is investigational in this setting.

New drug combination doubles effectiveness in shrinking enlarged spleens in myelofibrosis patients

Combining the JAK inhibitor ruxolitinib with the BCL-xL inhibitor navitoclax was twice as effective in reducing enlarged spleens – a major indicator of clinical improvement – compared with standard-of-care ruxolitinib monotherapy for adult patients with intermediate or high-risk myelofibrosis, a rare bone marrow cancer, according to results of the Phase III TRANSFORM-1 trial reported by researchers from The University of Texas MD Anderson Cancer Center.
