Detection of April in Human Blood Monocytes by Flow Cytometry.
Human peripheral blood monocytes stimulated with 5 ng/mL Recombinant Human IL-4 (Catalog # 204-IL) and 10 μg/mL Goat Anti-Human IFN‑ gamma Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-285-NA) for three days followed by a 3 hour incubation with monensin were stained with Mouse Anti-Human APRIL/TNFSF13 Monoclonal Antibody (Catalog # MAB8843) followed by Phycoerythrin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0102B) and Mouse Anti-Human CD4 APC-conjugated Monoclonal Antibody (Catalog # FAB3791A). Quadrant markers were set based on control antibody staining (Catalog # MAB004). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.

APRIL (a proliferation inducing ligand), also known as TNFSF13, TALL2, and TRDL1, is a member of the TNF ligand superfamily. It is synthesized as a 32 kDa type II transmembrane protein which is cleaved by furin in the Golgi to release a 17 kDa soluble molecule. Secreted APRIL consists almost entirely of a single TNF homology domain. Little or no transmembrane APRIL is expressed on the cell surface. Alternate splicing generates isoforms with short deletions at the N- or C‑terminus. Both APRIL and the closely related protein BAFF signal through the TNF superfamily receptors TACI and BCMA to promote cellular proliferation and protect from apoptosis. APRIL can form bioactive heterotrimers with BAFF. A bioactive cell surface-expressed protein known as TWEPRIL consists of the intracellular domain, transmembrane segment, and stalk region of TWEAK fused to the TNF homology domain of APRIL. Human APRIL shares 85% amino acid sequence identity with mouse and rat APRIL.
