  • La Jolla Institute Scientists Reveal Dual Role for T Cell Factor
    When fighting chronic viral infections or cancers, a key division of the immune system, known as CD8 T cells, sometimes loses its ability to effectively fight foreign invaders. Overcoming so-called T cell exhaustion is crucial to treating persistent infections but the ...More

  • UTSW Researchers Find New Mechanism That Controls Immune Responses
    UT Southwestern Medical Center researchers have identified a common signaling mechanism to produce interferon, one of the main proteins used to signal the immune system when the body needs to defend itself against a virus, tumor or other diseases. The findings are important ...More

  • Research Sheds Light on the Body's Defense Systems
    Researchers have uncovered a sieve-like structure in lymph nodes that regulates the transport of proteins and migration of white blood cells into lymph nodes. The discovery, made by scientists working at the University of Turku in Finland, will provide new insights into ...More

  • Skin-Based Immunity Secrets Revealed
    A team of international scientists has discovered a new mechanism by which immune cells in the skin function as the body's "border control," revealing how these cells sense whether lipid or fat-like molecules might indicate the presence of foreign invaders. The findings ...More

  • Vaccine-Induced CD4 T Cells Lead to Adverse Effect in a Mouse Model of Infection
    A study led by investigators at Beth Israel Deaconess Medical Center (BIDMC) has found that a vaccine that elicits only CD4 T cells against a mouse model of a chronic viral infection results in an overwhelming -- and lethal -- inflammatory response. Reported in the January ...More

  • Broad Immune Response May be Needed to Destroy Latent HIV
    A major barrier to finding a cure for HIV/AIDS is the presence of latent HIV in the cells of chronically infected individuals. But a team of Yale and Johns Hopkins researchers may have pinpointed a strategy for eliminating the residual virus. The study was published online ...More

  • New Technique Reveals Immune Cell Motion Through Variety of Tissues
    Neutrophils, a type of white blood cell, are the immune system’s all-terrain vehicles. The cells are recruited to fight infections or injury in any tissue or organ in the body despite differences in the cellular and biochemical composition. Researchers from Brown ...More

  • Scientists Identify New and Beneficial Function of Endogenous Retroviruses in Immune Response
    Retroviruses are best known for causing contagious scourges such as AIDS, or more sporadically, cancer. But researchers at UT Southwestern Medical Center and Karolinska Institutet in Stockholm, Sweden, found that endogenous retroviruses (ERV) also play a critical role in ...More

  • Once CD8 T Cells Take On One Virus, They'll Fight Others Too
    Scientists think of CD8 T cells as long-lived cells that become tuned to fight just one pathogen, but a new study finds that once CD8 T cells fight one pathogen, they also join the body's "innate" immune system, ready to answer the calls of the cytokine signals that are set ...More

  • Scripps Research Institute Scientists Identify Trigger for Crucial Immune System Cell
    Scientists at the Scripps Research Institute (TSRI) have identified the long-sought activating molecules for a rare but crucial subset of immune system cells that help rally other white blood cells to fight infection. In the process, the team also uncovered a previously ...More
