Special Issue Information
Dear Colleagues,
Antiretroviral therapy (ART) has greatly reduced HIV infection-associated morbidity and mortality. ART improved the lifespan of persons living with HIV infection by reducing viral replication, restoring CD4+ T cells and preventing the progression of HIV infection to acquired immunodeficiency syndrome (AIDS). However, despite long-term ART, low level of viral replication persists in HIV reservoirs residing in resting CD4+ T cells in the blood, central nervous system (CNS), gut-associated lymphoid tissue, bone marrow, and genital tract. Persisting low level viral replication in the ART controlled patients can contribute to sustained systemic immune activation and inflammation. ART reduces systemic inflammation and immune activation dramatically, but not to levels synchronous with HIV-uninfected populations. HIV proteins such as gp120 and Tat, secreted from HIV reservoirs, are capable of inducing generation of reactive oxygen species (ROS) which in turn can initiate immune activation/inflammation via production of cytokines and chemokines. Chronic inflammation has the potential to attenuate the efficacy of ART as well as promote pathological conditions and end-organ disease in HIV patients. Indeed in HIV patients on long-term ART, inflammation has been linked to cardiovascular disease (CVD), neurocognitive dysfunction, osteoporosis, cancer, muscle wasting, premature aging and frailty among others.
In this special issue we will focus on molecular mechanisms underlying persisting immune activation and inflammation in ART suppressed HIV infected patients, and also that are affecting various end-organ functions. Such comprehensive issue will deliver an overall understanding on the effect of inflammation on HIV and ART related diseases, and provide prospect for the development of therapeutics.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Biomolecules is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
