This approach could be used to treat early-stage HIV-infected individuals and potentially prevent infection.
Researchers develop novel approach to block HIV virus from invading white blood cells, potentially treating AIDS patients with genetic modification and reinfusion of immune-boosting lymphocytes. This strategy may provide a new paradigm for HIV treatment, protecting cells from infection rather than inhibiting replication.
The study aims to measure how effectively combination drug therapy works during the early stages of HIV infection, with a focus on reducing damage caused by the virus. Researchers hope to determine the optimal duration of treatment for maximum benefit and assess the impact of early treatment on immune system chemicals.
Scientists activate protein receptor to stimulate cell death in brain tumors, potentially sparing normal brain tissue. The therapy shows promise in treating nearly untreatable primary central nervous system lymphomas.
Researchers found that treating co-infections with sexually transmitted diseases (STDs) significantly reduces the amount of virus shed in semen, making transmission less likely. The study suggests widespread STD screening and therapy could be a crucial step in combating HIV/AIDS globally.
A new study reveals that tissue macrophages play a critical role in triggering the production of HIV in patients with AIDS, leading to increased virus levels despite declining CD4 T cell counts. This finding highlights the importance of controlling opportunistic infections to slow the cycle of virus production.
A study found thalidomide effective in healing 55% of HIV patients' mouth ulcers, while also improving comfort during eating. However, the treatment's potential for irreversible nerve damage and other side effects require careful monitoring.
Duke researchers found an existing class of drugs, cyclosporin and FK506, effectively stops the growth of the fungus Cryptococcus neoformans. The compounds are now being tested in animals with fungal infections.
Researchers have discovered that HIV can invade cells within any female reproductive tract organ, increasing the risk of infection. The study's findings suggest that vaccine development and disease prevention should aim to confer protection throughout the entire tract.
Scientists at Johns Hopkins Medicine report a test that counts AIDS viruses in blood can identify infected infants and extend their lives by starting treatment early. The test shows within a month after birth whether a baby born to an HIV-positive mother is also infected, allowing for prompt intervention.
Scientists measured viral load in 106 HIV-infected babies from birth to 5 years of age, finding that higher viral loads predict disease severity. Early HIV blood levels may also predict outcome of progression to AIDS in children, highlighting the need for early antiretroviral therapy.
Researchers identified three key factors that significantly boost the spread of HIV: having other STDs, multiple sexual relationships, and sex with people newly infected. Increasing STD detection and treatment, and focusing on early HIV infections can help curb the epidemic.
A potent chemokine, AOP-RANTES, has been shown to inhibit HIV-1 entry into macrophages and lymphocytes at the nanomolar level. Researchers believe this could lead to a new treatment approach for HIV/AIDS by targeting host cells to prevent viral entry.
Researchers have found that cidofovir, a new antiviral drug, can slow the progression of cytomegalovirus (CMV) retinitis, a common cause of vision loss and blindness in AIDS patients. The study showed that both low and high doses of the drug were effective, allowing for less frequent treatment compared to traditional options.
Researchers found that HIV-infected immune cells take in more vitamin C and glucose than healthy counterparts, but extremely high levels are toxic. This study provides a foundation to understand the relationship between vitamin C, HIV infection, and cell metabolism.
Researchers have discovered that different strains of HIV may exploit distinct immune cells through chemokine coreceptors, potentially explaining the sudden collapse of the immune system in full-blown AIDS patients. The findings could lead to new treatments by targeting these receptors.
