A new study describes the complexity of the new T cell repertoire following immune-depleting therapy to treat multiple sclerosis, improving our understanding of immune tolerance and clinical outcomes. In the Immune Tolerance Network's (ITN) HALT-MS study, 24 patients with relapsing, remitting multiple sclerosis received high-dose immunosuppression followed by a transplant of their own stem cells, called an autologous stem cell transplant, to potentially reprogram the immune system so that...

Newborns are more susceptible to infections, presumably because of their immature and inexperienced immune systems. The most common dangerous condition in newborns and infants are lower respiratory tract infections caused by viruses, especially respiratory syncytial virus (RSV). A study published on February 13th in PLOS Pathogens shows how the immune system in the lungs during early life differs from the one in older children and adults. Ideally, newborns could be protected against RSV by...

Researchers use a naturally occurring HIV variant to trace a T cell lineage for 17 years WHAT: A team of researchers has reported a novel method for tracking CD4+ T cells in people infected with HIV. CD4+ T cells are critical for immune defense against an array of pathogens and are a primary target of HIV. In the study, researchers used a unique, replication-incompetent (defective) form of HIV identified in a patient in the early 1990s. The defective virus had integrated into the genome...

Nearly half of HIV-infected teenagers and young adults forego timely treatment, delaying care until their disease has advanced, which puts them at risk for dangerous infections and long-term complications, according to a study led by the Johns Hopkins Children's Center. The researchers say their findings, published Feb. 3 in JAMA Pediatrics, are particularly troubling in light of mounting evidence that starting treatment as early as possible can go long way toward keeping the virus in...

Scientists Discover How Immune Cells Die During HIV Infection And Identify Potential Drug To Block AIDS
2013-12-20 13:04:27

Gladstone Institutes Research led by scientists at the Gladstone Institutes has identified the precise chain of molecular events in the human body that drives the death of most of the immune system's CD4 T cells as an HIV infection leads to AIDS. Further, they have identified an existing anti-inflammatory drug that in laboratory tests blocks the death of these cells—and now are planning a Phase 2 clinical trial to determine if this drug or a similar drug can prevent HIV-infected people...

St. Jude Children’s Research Hospital scientists find mechanism that launches production of the specialized T cells essential for combating infectious agents and that offers new therapeutic possibilities Memphis, Tenn. (PRWEB) December 16, 2013 St. Jude Children’s Research Hospital scientists have identified a protein complex that is essential for jumpstarting the immune response during the critical first 24 hours of an infection. The research appears in the current issue of the...

In many ways, the spread of HIV has been fueled by substance abuse. Shared needles and drug users' high-risk sexual behaviors are just some of the ways that narcotics such as cocaine have played a key role in the AIDS epidemic in much of the world. There is, however, relatively little research into how drugs can impact the body's defenses against the virus. But a new UCLA study published in the October issue of the Journal of Leukocyte Biology examines how cocaine affects a unique...

New research published in the Journal of Leukocyte Biology suggests that cocaine makes quiescent CD4 T cells susceptible to HIV resulting in significant infection and new virus production Cocaine use may increase one's vulnerability to HIV infection, according to a new research report published in the Journal of Leukocyte Biology. In the report, scientists show that cocaine alters immune cells, called "quiescent CD4 T cells," to render them more susceptible to the virus, and at the same...

HIV-infected people who carry a gene for a specific protein face a 20-fold greater risk of contracting cryptococcal disease, according to a study published in mBio®, the online open-access journal of the American Society for Microbiology. Cryptococcus neoformans is the most common cause of fungal meningitis among HIV-infected individuals. While the disease is a risk for everyone with HIV who has a very low level of CD4+ T cells, researchers have discovered that those with the gene for the...
