The present study aimed to investigate the effects of lentiviral infection of human umbilical cord mesenchymal stem cells (hUCMSCs) on the expression of octamer transcription factor 4 (Oct4). hUCMSCs were infected with lentivirus carrying the green fluorescent protein gene (GFP) at different multiplicities of infection (MOI), and the optimal MOI was determined by flow cytometry; the proliferati...

Systemic inflammatory response syndrome is a pathophysiological inflammatory response mediated largely by tumor necrosis factor‑α (TNF‑α), in response to infectious or non‑infectious stimuli. TNF‑α secretion in response to bacterial lipopolysaccharide (LPS) is regulated in part by disintegrin and metalloproteinase domain‑containing protein 17 (ADAM17). Therefore, the present study aimed to iden...

SARS-CoV-2 uses the human ACE2 (hACE2) receptor for cell attachment and entry, with mouse (mACE2) unable to support infection. Herein we describe an ACE2-lentivirus system illustrate its utility in vitro vivo infection models. Transduction of non-permissive lines hACE2 imparted replication competence, transduction mACE2 containing N30D, N31K, F83Y H353K substitutions, match hACE2, rescued repli...

Caprine arthritis encephalitis virus (CAEV) is a lentivirus that infects both goats and sheep and is closely related to maedi-visna virus that infects sheep; collectively, these viruses are known as small ruminant lentiviruses (SRLV). Infection of goats and sheep with SRLV typically results in discrete inflammatory diseases which include arthritis, mastitis, pneumonia or encephalomyelitis. SRLV...

OBJECTIVES The role of the NLRP3 inflammasome in atherosclerosis remains controversial. The aim of this study was to determine whether inhibition of NLRP3 signaling by lentivirus-mediated RNA interference could reduce atherosclerosis and stabilizes plaques. We also tried to explore the mechanisms of the impact of NLRP3 inflammasome on atherosclerosis. METHODS Apolipoprotein E-deficient mice a...

Feline immunodeficiency virus (FIV) is a lentivirus of domestic cats that shares several similarities with its human counterpart, human immunodeficiency virus (HIV). Their analogies include genomic organization, lymphocyte tropism, viral persistence and induction of immunodeficiency. FIV is the only lentivirus for which a commercial vaccine is registered for prevention in either human or veteri...

Clusterin (CLU) is a glycoprotein that is over-expressed in a number of malignant tumors and has been proven to correlate closely with the chemoresistance of several cancer cells to chemotherapeutic agents. However, the effect of CLU expression on the chemoresistance of bladder cancer to epirubicin remains unknown. In the present study, we aimed t...
