Inhibitors of NAMPT have anti-inflammatory and anticancer activity and are finding use as therapeutic agents. In view of the importance of NAD metabolism in neutrophil function, we determined the effects of NAMPT inhibition on a variety of neutrophil functions associated with their role in host protection against infections. Incubation of human neutrophils with the NAMPT inhibitor APO866 decreased neutrophil NAD(P)\/H levels in a dose- and time-dependent manner but without a concomitant change in cell viability. NAMPT inhibition did not affect the expression of a number of cell-surface receptors involved in adhesion and opsono-phagocytosis, but the respiratory burst was decreased significantly. Whereas opsono-phagocytosis of Staphylococcus aureus was unaffected by NAMPT inhibition, intraphagosomal oxidant production was decreased. However, the killing efficiency of neutrophils was unaffected. These data indicate that therapeutic NAMPT inhibition is unlikely to have deleterious effects on host protection against infections, in spite of this ability to down-regulate neutrophil respiratory burst activity significantly.<\/jats:p>","DOI":"10.1189\/jlb.1012527","type":"journal-article","created":{"date-parts":[[2013,6,27]],"date-time":"2013-06-27T04:36:24Z","timestamp":1372307784000},"page":"481-492","source":"Crossref","is-referenced-by-count":19,"title":["Inhibition of pre-B cell colony-enhancing factor (PBEF\/NAMPT\/visfatin) decreases the ability of human neutrophils to generate reactive oxidants but does not impair bacterial killing"],"prefix":"10.1093","volume":"94","author":[{"given":"Kate J","family":"Roberts","sequence":"first","affiliation":[{"name":"Institutes of Integrative Biology, University of Liverpool , United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Cross","sequence":"additional","affiliation":[{"name":"Aging and Chronic Disease, University of Liverpool , United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olga","family":"Vasieva","sequence":"additional","affiliation":[{"name":"Institutes of Integrative Biology, University of Liverpool , United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert J","family":"Moots","sequence":"additional","affiliation":[{"name":"Aging and Chronic Disease, University of Liverpool , United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven W","family":"Edwards","sequence":"additional","affiliation":[{"name":"Institutes of Integrative Biology, University of Liverpool , United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2013,6,26]]},"reference":[{"key":"2023032711575781000_","doi-asserted-by":"crossref","first-page":"10","DOI":"10.1016\/0952-7915(89)90091-5","article-title":"The neutrophil","volume":"2","author":"Haslett","year":"1989","journal-title":"Curr.
