HIV and Host Interactions Ⅱ

Dear Colleagues,

HIV and human defense mechanisms have co-evolved to neutralize each other. In the course of infection, HIV exploits the cellular equipment and inhibits the action of antiviral proteins (termed “restriction factors”). Not everyone exposed to the virus becomes infected, and there is considerable heterogeneity in the clinical course of HIV infection, with some people progressing rapidly to disease and death while others show no signs of immunodeficiency for decades. These individuals exhibit immunological and genetic features that confer upon them a natural resistance to infection and/or disease progression. The study of these correlates of protection is valuable because the reasons responsible for the devastating immune deficiency of HIV-1 infection are not entirely unveiled, nor are we aware why the potent antiviral immune response eventually fails to control viral replication. Despite HIV’s ability to evade host restriction factors, the detection of these determinants and understanding of how they interact with viral accessory proteins provide remarkable insight into the potential mechanisms involved in the pathogenesis of HIV-1 infection. The discovery of molecular profiles and mechanisms distinctive of these individuals could also provide new insights to control HIV infection and contribute to the development of new antivirals and hopefully vaccines against AIDS.

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 250 words) can be sent to the Editorial Office for assessment.

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. Cells is an international peer-reviewed open access semimonthly 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.
