    (1) RAI Services, Winston-Salem, NC, USA; (2) Wake Forest University, Winston-Salem, NC, USA; (3) Quire Inc., Memphis, TN, USA
    Cigarette smoking exerts diverse physiological effects including immune suppression. Existing epidemiological data show that consumption of smokeless tobacco products, such as moist snuff, is less harmful relative to smoking. We previously demonstrated ...

    Differential gene expression and functional responses in peripheral blood mononuclear cells pretreated with combustible and non-combustible tobacco products

    TRAN Q.T.(1); ARIMILLI S.(2); LIU Gang(1); MAKENA P.(1); PRASAD G.L.(1)
    (1) RAI Services Company, Winston-Salem, NC, USA; (2) Wake Forest School of Medicine, Winston-Salem, NC, USA
    Chronic smoking is known to alter immune responses, which compromises tumor surveillance and host defense against microbial infections. We previously showed that smokers (SMK) exhibit distinct peripheral blood mononuclear cell (PBMC) gene expression ...

    Combustible and smokeless tobacco product preparations differentially regulate calcium mobilization in the human leukemic HL60 cell line

    MAKENA P.(2); ARIMILLI S.(1); DAMRATOSKI B.E.(1); PRASAD G.L.(2)
    (1) Wake Forest University School of Medicine, Department of Microbiology & Immunology, Winston-Salem, NC, U.S.A.; (2) RAI Services Co., Winston-Salem, NC 27102, U.S.A.
    Increased calcium (Ca 2+) mobilization is central to leukocyte signaling and for regulation of immune responses. Although evidence suggests that cigarette smoking affects several biological functions including inflammatory responses, how the use of ...

    Role of oxidative stress in the suppression of immune responses in peripheral blood mononuclear cells exposed to combustible tobacco product preparations

    PRASAD G.L.(1); ARIMILLI S.(2); DAMRATOSKI B.E.(2)
    (1) Scientific & Regulatory Affairs, RAI Services Company, Winston-Salem, U.S.A.; (2) Department of Microbiology & Immunology, Wake Forest University Health Sciences, U.S.A.
    Cigarette smoking is a major risk factor for several human diseases. Chronic inflammation, resulting from increased oxidative stress, has been suggested as a mechanism that contributes to the increased susceptibility of smokers to cancer and microbial ...

    Ex vivo effects of smokeless tobacco extracts on select immune responses

    PRASAD G.L.(1); ARIMILLI S.(2); DAMRATOSKI B.E.(2); SCHMIDT E.(1); ROWE J.(3); CHOUCHANE S.(4)
    (1) RAI Services Company; (2) Wake Forest University Health Sciences; (3) R.J. Reynolds Tobacco Co.; (4) Eurofins Lancaster Labs Inc, Winston-Salem, NC, USA
    Our previous work demonstrated that exposure to Tobacco Product Preparations (TPPs) from combustible tobacco cause cytotoxic and select immunosuppressive effects in PBMCs, and this ex vivo model is well suited to investigate the chronic immune suppression ...
