Interests: the role and mechanism of NK cells in viral infection; mechanism of NK in controlling early virus replication and transmission; the mechanisms by which NK cells recognize virus infected cells; the role of different subgroups of NK cell during viral infection; the functional change of NK cells with aging; the impact and mechanism of NK cell response on subsequent T and B cell responses

Special Issue Information

Dear Colleagues,

NK cells are a critical cell population in innate immunity, playing roles in antiviral and anti-tumor immunity. Nevertheless, how NK cells function to address these challenges remains poorly understood. Meanwhile, NK cell function declines with aging, which has a critical impact on overall immunity in the elderly. Understanding the molecular and cellular mechanisms involved in NK cell activation, expansion, and memory will reveal possible pathways to enhance NK cell function and enhance immunity against viral infections. The goal of this Special Issue of Viruses is to explore interactions between NK cells and viruses.

Primary research and review articles pertaining to virus interactions with NK and NK-related immune populations are invited. Topics of interest include, but are not limited to, the following:

  1. Innate recognition of NK cells during viral infection;
  2. Generation and regulation of NK cell memory;
  3. Defects in NK cell function with aging and viral infection.

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. Viruses 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 2600 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.

Background and Aims: The outcomes of HBV infections are related to complex immune imbalances; however, the precise mechanisms by which HBV induces immune dysfunction are not well understood. Methods: HBV transgenic (HBs-Tg) mice were used to investigate intrahepatic NK cells in two distinct subsets: conventional NK (cNK) and liver-resident NK (LrNK) cells during a chronic HBV infection. Results: The cNK cells, but not the LrNK cells, were primarily responsible for the increase in the number of bulk NK cells in the livers of ageing HBs-Tg mice. The hepatic cNK cells showed a stronger ability to produce IL-10, coupled with a higher expression of CD69, TIGIT and PD-L1, and lower NKG2D expression in ageing HBs-Tg mice. A lower mitochondrial mass and membrane potential, and less polarized localization were observed in the hepatic cNK cells compared with the splenic cNK cells in the HBs-Tg mice. The enhanced galectin-3 (Gal-3) secreted from HBsAg+ hepatocytes accounted for the IL-10 production of hepatic cNK cells via ITGB1 signaling. For humans, LGALS3 and ITGB1 expression is positively correlated with IL-10 expression, and negatively correlated with the poor clinical progression of HCC. Conclusions: Gal-3-ITGB1 signaling shapes hepatic cNK cells but not LrNK cells during a chronic HBV infection, which may correlate with HCC progression. Full article
