Interleukin-4 (IL-4), also known as B cell-stimulatory factor-1, is a monomeric, approximately 13-18 kDa Th2 cytokine that shows pleiotropic effects during immune responses (1‑3). It is a glycosylated polypeptide that contains three intrachain disulfide bridges and adopts a bundled four alpha -helix structure (4). Human IL-4 is synthesized with a 24 aa signal sequence. Alternate splicing generates an isoform with a 16 aa internal deletion. Mature human IL-4 shares 55%, 39%, and 43% aa sequence identity with bovine, mouse, and rat IL-4, respectively. Human, mouse, and rat IL-4 are species-specific in their activities (5-7). IL-4 exerts its effects through two receptor complexes (8, 9). The type I receptor, which is expressed on hematopoietic cells, is a heterodimer of the ligand binding IL-4 R alpha and the common gamma chain (a shared subunit of the receptors for IL-2, -7, -9, -15, and -21). The type II receptor on non-hematopoietic cells consists of IL-4 R alpha and IL-13 R alpha 1. The type II receptor also transduces IL-13 mediated signals. IL-4 is primarily expressed by Th2-biased CD4+ T cells, mast cells, basophils, and eosinophils (1, 2). It promotes cell proliferation, survival, and immunoglobulin class switch to IgG4 and IgE in human B cells, acquisition of the Th2 phenotype by naïve CD4+ T cells, priming and chemotaxis of mast cells, eosinophils, and basophils, and the proliferation and activation of epithelial cells (10-13). IL-4 plays a dominant role in the development of allergic inflammation and asthma (12, 14).

Cell Proliferation Induced by IL‑4 and Neutralization by Human IL‑4 Antibody.
Recombinant Human IL-4 (Catalog # 204-IL) stimulates proliferation in the TF-1 human erythroleukemic cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human IL-4 (0.5 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human IL-4 Monoclonal Antibody (Catalog # MAB204). The ND50 is typically 0.5-1.5 µg/mL.Detection of IL-4 by Western Blot
IL-12 does not inhibit 1,25(OH)2D3 production or VDR expression and function in CD4+ T cells. Relative CYP27B1 (A), VDR (C), and CYP24A1 (E) expression in T cells activated for 72 h in the presence of 100 nM 25(OH)D3 and the indicated concentration of IL-12. Data are normalized to activated T cells incubated with 100 nM 25(OH)D3 in the absence of IL-12 (mean + SEM, n ≥ 6). (B) 1,25(OH)2D3 production in T cells activated for 72 h in the presence of 100 nM 25(OH)D3 and the indicated concentration of IL-12 (mean + SEM, n ≥ 4). (D) Representative Western blot (lower panel) and quantification (upper panel) of VDR with GAPDH as loading control from T cells activated for 72 h in the presence of 100 nM 25(OH)D3 and in the presence or absence of 10 ng/ml IL-12 (mean + SEM, n = 4).
