New immunity cells known as CD11c+ dendritic cells have been identified by a team of researchers from The Westmead Institute For Medical Research in Sydney.These CD11c+ dendritic cells are extremely susceptible to the HIV virus and can transmit the virus to other cells especially the CD4 T Cells. These CD11c+ dendritic cells are a type of dendritic cells that play a role in capturing any i...

Most HIV patients have a 60% risk of developing a form of cancer during their life-span. Cancers like Lymphoma, Lung Cancer, Anal Cancer, Cervical Cancer, Oral and oropharyngeal cancer ,liver cancer, skin cancer and also Kaposi's sarcoma are most prevalent among HIV patients.  At the recent ASCO presentation, study led by doctors at Fred Hutchinson Cancer Research Center showed that pati...

A new HIV vaccine delivery strategy appears to enhance the protective immune response in a preclinical model. Scientists at the La Jolla Institute for Immunology (LJI) have discovered that delivering an HIV vaccine in small doses over a series of days leads to a stronger immune response than when the same vaccine is given all at once.   A similar escalating dose method could be the best way...

Regular infusions of an antibody that blocks the HIV binding site on human immune cells may have suppressed levels of HIV for up to four months in people undergoing a short-term pause in their antiretroviral therapy (ART) regimens, according to a report published online today in The New England Journal of Medicine. Results of the Phase 2, open-label study indicate the antibody, known as UB-42...

A recent research found that long-term cotrimoxazole treatment reduces mortality and morbidity in children with HIV by altering their gut microbiome and immune activation. The finding supports current WHO guidelines, which recommend long-term cotrimoxazole treatment for all HIV-positive people living in areas where malaria and severe bacterial infections are common. Previous studies have shown...

George Mason University's Yuntao Wu is the lead scientist on a research team that has identified a measurable indicator that could prove instrumental in the fight against HIV. The research focuses on cofilin, a key protein that regulates cells to mobilize and fight against infection. In an HIV-infected patient, cofilin dysfunction is a key factor in helper T cell defects, according to the r...

The immune system is the body's best defense in fighting diseases like HIV and cancer. Now, an international team of researchers is harnessing the immune system to reveal new clues that may help in efforts to produce an HIV vaccine.     SFU professor Mark Brockman and co-authors from the University of KwaZulu-Natal in South Africa have identified a connection between infection cont...

Researchers can now quickly and accurately count a hidden, inactive form of the human immunodeficiency virus (HIV) that lurks in patients' cells. This version of HIV embeds into cells' genomes and can persist despite otherwise successful therapies, thwarting attempts to cure the infection. Using a new genetic technique developed by Howard Hughes Medical Institute Investigator Robert Sil...

Much of the research on HIV has focused on preventing infection but little is understood about how the body keeps the virus in check post-infection. A new study by Yale investigators reveals the role of a protein that serves to block HIV gene expression once it has entered human cells. The research team, led by Manabu Taura, a postdoctoral fellow in the laboratory of immunobiologist  ...

A study from a Massachusetts General Hospital (MGH) research team has identified the specific function of a protein found in HIV and related viruses that appears to slow down viral spread in the earliest stages of infection. But they also found that, after initially slowing down the spread of infection, that function may help the virus survive later on by evading the immune response. Their report ...

Current HIV treatments need to be taken for life by those infected as antiretroviral therapy is unable to eliminate viral reservoirs lurking in immune cells. Institut Pasteur scientists have identified the characteristics of CD4 T lymphocytes that are preferentially infected by the virus – it is their metabolic (or energy-producing) activity1 that enables the virus to multiply. Thanks to met...

A new study has shown that HIV-infected men had lower median bone mineral density (BMD) scores at the hip compared to HIV-uninfected men, and all men who received testosterone had significantly greater BMD scores at the lumbar spine. Further, in HIV-infected men with virologic suppression testosterone was significantly associated with a higher BMD score at the lumbar spine, as reported in AID...

Of the 50 million people around the world infected with HIV, less than one per cent have immune systems strong enough to suppress the virus for extended periods of time. These special immune systems are known as "elite controllers." But how do they actually fight HIV? Canadian scientists think they've found an important clue. TRIM5 Alpha protein Working in collaboration with a team...

Researchers at Johns Hopkins have identified two patients with HIV whose immune cells behave differently than others with the virus and actually appear to help control viral load even years after infection. Moreover, both patients carry large amounts of virus in infected cells, but show no viral load in blood tests. While based on small numbers, the data suggest that long-term viral remission migh...

Mechanisms that govern HIV transcription and latency differ in the gut and blood, according to a study published November 15 in the open-access journal PLOS Pathogens by Steven Yukl of San Francisco Veterans Affairs Medical Center and the University of California, San Francisco, and colleagues. According to the authors, the findings could inform new therapies aimed at curing HIV. HIV R...

A small percentage of patients, some of whom have taken many HIV drugs in the past, have multidrug-resistant HIV, limiting their treatment options   HIV naturally mutates and eventually develops resistance to ARVs, which are then rendered ineffective. Patients infected with drug resistant strains of HIV are therefore commonly moved to alternative regimens known as 2nd line drugs. &n...

People living with HIV must take a combination of three or more different drugs every day for the rest of their lives. Unfortunately, by following this strict treatment plan, they can suffer from side effects ranging from mild dizziness to life-threatening liver damage. However, if they stop taking the drugs, the virus hiding inside their cells can spontaneously resurface.   In fact...
