Extrapolating from the effects on minocycline on rheumatoid arthritis patients showing the anti-inflammatory effects of minocycline on T cells, John Hopkins group researchers found that minocycline treatment had multiple beneficial effects in monkeys infected with SIV, the primate version of HIV. In monkeys treated with minocycline, the virus load in the cerebrospinal fluid, the viral RNA in the brain and the severity of central nervous system disease were significantly decreased. The drug was also shown to affect T cell activation and proliferation.
Hopefully it can act in conjunction with antiretroviral drugs to control HIV infections.
ScienceDaily (Mar. 20, 2010) — Johns Hopkins scientists have found that a safe and inexpensive antibiotic in use since the 1970s for treating acne effectively targets infected immune cells in which HIV, the virus that causes AIDS, lies dormant and prevents them from reactivating and replicating.
The drug, minocycline, likely will improve on the current treatment regimens of HIV-infected patients if used in combination with a standard drug cocktail known as HAART (Highly Active Antiretroviral Therapy)...Unlike the drugs used in HAART which target the virus, minocycline homes in on, and adjusts T cells, major immune system agents and targets of HIV infection. According to Clements, minocycline reduces the ability of T cells to activate and proliferate, both steps crucial to HIV production and progression toward full blown AIDS.
If taken daily for life, HAART usually can protect people from becoming ill, but it's not a cure. The HIV virus is kept at a low level but isn't ever entirely purged; it stays quietly hidden in some immune cells. If a person stops HAART or misses a dose, the virus can reactivate out of those immune cells and begin to spread.
