Cd4 t cells

Pacritinib was provided by CTI BioPharma Corp. (Seattle, WA, USA). Ruxolitinib, fedratinib, and momelotinib were obtained from Selleckchem (Houston, TX, USA). Primary human endothelial cells (HuVEC), neonatal foreskin fibroblasts (HDFn), bronchial epithelial cells (BE), coronary arterial smooth muscle cells (CASMC), and keratinocytes (HEK) were obtained from Lonza, Lifeline Cell Technologies and Cell Applications. Peripheral blood mononuclear cells (PBMCs) and positively selected primary normal human CD19+ B cells, CD4+ T cells, and CD14+ monocytes were purchased (AllCells, Emeryville, CA) or were isolated in-house (LeukoPak [StemCell and Physicians Plasma Alliance]). All primary cells were obtained under protocols that were reviewed by Institutional Review Board(s) that operate in accordance with the requirement of EPA Regulation 40 CFR 26 and HHS Regulation 45 CFR 46 of the US Department of Health and Human Resources for the protection of human research subjects. Stimuli include recombinant human IFNγ, TNFα, and IL-1β, IL-4, PDGF, FGF, EGF, and TGFβ (Peprotech, SEB, and TSST [Toxin Technologies]) Histamine, LPS, (Sigma), anti-human IgM (Southern Biotechnology), and Zymosan (Invivogen). Mouse detection antibodies against human biomarkers were obtained from commercial sources, including BD BioSciences, Sigma, and R&D Systems.

CD4+ T cells, CD19+ B cells and neutrophils from venous blood of a healthy Caucasian male donor were purchased from AllCells Company (AllCells, Alameda, California). The use of the cells for research purpose has AllCells company IRB approval (Biomed IRB). The donor signed the written consent form, which is archived with their medical records. All experiments were performed in accordance with relevant guidelines and regulations. According to US Federal Regulations, 45 CFR Part 46.101(b)(4)–Protection of Human Subjects, using this type of human cells for research is exempted from the requirement for IRB review.
