Immune resilience promotes longevity and resistance to infections

Researchers from The University of Texas Health Science Center at San Antonio, working with collaborators in five countries, today revealed that the capacity to resist or recover from infections and other sources of inflammatory stress - called "immune resilience" - differs widely among individuals.

Antiretroviral treatment efficiently suppresses penile HIV replication

Of the 38 million people worldwide living with HIV, approximately 700,000 are newly infected men, primarily via sexual transmission.

Study raises new hopes for blood cancer patients with an incomplete response to CAR T cell therapy

The aim of immunotherapy strategies is to use cells in the patient's own immune system to destroy tumor cells. CAR T cell therapy is an immunotherapy that is effective in treating blood cancer.

Scientists identify the IL-17 protein as a determining factor in skin aging

A team of scientists from the Institute for Research in Biomedicine (IRB Barcelona) in collaboration with the National Center for Genomic Analysis (CNAG) has discovered that IL-17 protein plays a central role in skin aging.

Microparticle-delivered therapy likely to be the first step toward stopping autoimmune diseases

According to the federal government's National Institute of Neurological Disorders and Stroke, nearly 3 million people worldwide - with almost a third in the United States - are living with multiple sclerosis (MS), a disabling neurological disease in which the body's immune system mistakenly attacks nerves feeding information to the central nervous system (the brain and spinal cord). Although rarely fatal, MS can lead to long-term disabilities, and impair movement, muscle control, vision and cognition.

Multiple sclerosis: Immune cell invasion enabled by blood-brain barrier breakdown

Blood-brain barrier breakdown in multiple sclerosis leads to immune cell infiltration into the central nervous system. Antigen presentation at the barrier promotes CD8+ T cell entry, triggering focal breakdown and hindering their invasion.

Scientists investigate how immune system's T cells could fight many coronaviruses at once

Scientists at La Jolla Institute for Immunology (LJI) are investigating how the immune system's T cells react to a wide variety of coronaviruses, ranging from SARS to common cold coronaviruses.

New method may help identify the essential ingredients for making an effective HIV vaccine

Since it was identified in 1984 as the cause of Acquired Immune Deficiency Syndrome (AIDS), the human immunodeficiency virus (HIV) has infected more than 80 million people and been responsible for some 40 million deaths worldwide, according to the World Health Organization (WHO).

Study shows the potential of TAp63 as a new therapeutic target for rheumatoid arthritis

Rheumatoid arthritis (RA) is an autoimmune disease characterized by joint deterioration. The clinical outcomes of patients with active RA can be improved using anti-rheumatic medications, such as methotrexate (MTX).

Cross-reactivity between Epstein-Barr virus and protein in multiple sclerosis sheds light on disease development

Research uncovers the association between multiple sclerosis (MS) and antibody reactivity to specific amino acids in CRYAB, along with the increased risk when combined with high EBNA1 responses. The study provides evidence of antibody and T cell cross-reactivity between EBNA1 and CRYAB, highlighting the role of EBV adaptive immune responses in MS development.
