The inflammation caused by the cytokines helps to wake up T cells that had formally been dormant and that contain HIV genetic material, said Markus Haug, a staff scientist at CEMIR and co-first author of the study.
In this Aug. Willis is one of thousands of Americans who were rescued from the brink of death by the advent of the AIDS cocktail, a combination of pills that turned a uniformly lethal disease into a treatable one. These days, the number of pills an HIV patient needs to take has dropped dramatically, but long-term treatment has led to other health problem, including a phenomenon called inflam-aging.
In other words, the TLR8 signal and cytokine-induced inflammation shock the HIV out of the dormant cells — where it can be destroyed. The destruction of HIV by endosomes and the associated inflammation may also be one reason why patients who have been on antiretroviral treatments for decades are now beginning to develop inflammatory diseases more commonly associated with people decades older.
He is also an author on the paper. However, we are not able to eradicate the virus and just weeks after patients stop medication the virus will reappear from virus reservoirs.
Moreover, their findings may also represent major step forward in vaccine development as TLR8 ligands could be used as vaccine adjuvants that shape the type of T cell responses that is induced by the vaccine.

Now they are also using this approach to better understand the human body — including the causes behind high blood pressure. Even the least severe forms of sexual harassment can have serious consequences for high school students who are targeted.

Yu says her team hopes to capitalise on the discovery by seeking ways to make dendritic cells from ordinary patients mimic the HIV response seen in elite controllers. They are now screening novel molecules and adjuvants — substances given alongside vaccines — to identify any that do the trick. These could then be tested to see if they provide the extra kick needed to prime the immune system against HIV. Jones and his colleagues uncovered potential reasons why one such class of drugs, called histone deacetylase HDAC inhibitors, have not been successful in clinical trials.
The ultimate goal of latency reversal in such trials is to cause reservoir cells to produce HIV antigens, which are foreign substances to which the immune system mounts a response. The team reported that, while HDAC inhibitors stimulated one important step in the production of antigens, this did not proceed to completion and thus did not trigger immune cells.
