IL‑5 in Human Peripheral Blood Lymphocytes. IL‑5 was detected in immersion fixed human peripheral blood lymphocytes using Mouse Anti-Human IL‑5 Monoclonal Antibody (Catalog # MAB605) at 5 µg/mL for 3 hours at room temperature. Cells were stained (red) and counterstained (green). Specific labeling was localized to the cytoplasm of PBMCs. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Detection of IL‑5 in PMA and Ca2+ionomycin-treated Human PBMCs by Flow Cytometry. Human PBMCs, untreated (light orange filled histogram) or activated with 50 ng/mL PMA and 500 ng/mL Ca2+ionomycin for 5 hours (dark orange filled histogram), were stained with Human IL-5 Monoclonal Antibody (Catalog # MAB605) or isotype control antibody (Catalog # MAB002, open histogram), followed by Fluorescein-conjugated Anti-Mouse IgG F(ab')2Secondary Antibody (Catalog # F0103B). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.

Background: IL-5

Interleukin-5 (IL-5) is a secreted glycoprotein that belongs to the alpha -helical group of cytokines (1 ‑ 3). Unlike other family members, it is present as a covalently linked antiparallel dimer (4, 5). The cDNA for human IL-5 encodes a signal peptide and a 115 amino acid (aa) mature protein. Mature human IL-5 shares 70%, 70%, 62%, 71%, 70% and 66%, aa sequence identity with mouse, rat, canine, equine, feline and porcine IL-5, respectively and shows cross‑reactivity with mouse IL-5. IL-5 is primarily produced by CD4+ Th2 cells, but also by activated eosinophils, mast cells, EBV-transformed B cells, Reed-Sternberg cells in Hodgkin’s disease, and IL‑2‑stimulated invariant natural killer T cells (iNKT) (1 ‑ 3, 6 ‑ 8). IL-5 increases production and mobilization of eosinophils and CD34+ progenitors from the bone marrow and causes maturation of eosinophil precursors outside the bone marrow (1, 6, 9, 10). The receptor for human IL-5, mainly expressed by eosinophils, but also found on basophils and mast cells, consists of a unique ligand-binding subunit (IL-5 R alpha ) and a shared signal‑transducing subunit, beta c (3, 6, 11). IL-5 R alpha first binds IL-5 at low affinity, then associates with preformed beta c dimers, forming a high-affinity receptor (12). IL-5 also binds proteoglycans, potentially enhancing its activity (13). Soluble forms of IL-5 R alpha   antagonize IL-5 and can be found in vivo (10, 14). In humans, IL-5 primarily affects cells of the eosinophilic lineage, and promotes their differentiation, maturation, activation, migration and survival, while in mice IL-5 also enhances Ig class switching and release from B1 cells (1 ‑ 3, 9, 10, 15, 16). IL-5 also promotes differentiation of basophils and primes them for histamine and leukotriene release (17).
