Chimps Not Immune to HIV

A team of researchers have discovered that chimpanzees in Tanzania die from a disease that is similar to AIDS, which they hope could lead to new insights about the disease and eventually to the development of a HIV vaccine.The nine-year study, which was published in the British research journal Nature, showed that chimps that are infected by certain strains of Simian Immunodeficiency Virus (or SIV, the precursor to HIV), die 10 to 16 times more frequently compared to uninfected chimps.The findin…

Women Are Naturally Weaker to HIV

A recent US study shows that HIV reacts differently among women compared to men.  While HIV progresses faster in women than in men who have similar levels of HIV in the blood, the study has found that a receptor molecule involved in the first-line recognition of HIV responds differently in women.According to the study conducted by the researchers at the Massachusetts General Hospital, which was published in Nature Medicine, a higher percentage of our immune system’s frontline cells became activa…

Travel Ban for HIV Patients in United States to Be Lifted

The United States Senate has voted to overturn a two-decade law that bans people living with HIV from entering the country.  The Advocate magazine, which reports about gay and lesbian concerns, has also reported that new regulations have been issued by the United States Department of Health and Human Services that would lift restrictions against nonimmigrant visas for people with HIV and AIDS.  The office has removed HIV from the list of diseases that made visitors ineligible for entry to the co…

Scientists Banking on Treatment of “Sanctuary Cells” Lead to HIV Cure

A team of Canadian and American researchers have found a new way to fight, and possibly eradicate, HIV.  The new method combines antiretroviral therapy, which is the current treatment for HIV, with what they refer as “intelligent targeted chemotherapy.”Introduced in the mid-1990s, antiretroviral treatment aims to block the virus.  It has enabled patients with HIV to live longer instead of dying within the next five years.  However, this treatment only diminishes the number of HIV-infected cells …
