Gating strategies used to select specific leukocytes subpopulations.
The lymphocytes were identified as R1 based on their size and granularity flow cytometric features prior to the analysis of CD8+, CD4+, CD21+ lymphocytes subsets identified as R2 and proliferation. Lymphocytes subpopulations expressing the memory marker (CD45RO) were quantified based on R3. The mean of fluorescence intensity of MHC class II on lymphocytes subpopulations were quantified based on R4. Percentage of lymphocytes subsets expressing intracytoplasmic cytokines (IFN-γ, IL-17A and IL-4) or cytotoxic markers (perforin and granzyme B) were quantified based on Q1. Percentage of lymphocytes subsets expressing FoxP3-CD25 was determined using quadrant statistics over anti-Foxp3 versus anti-CD25 marker dot plot distribution (Q2). For proliferation assay, the phenotypic analysis was carried to determine the percentage of divided cells using CFSE/anti-bovine surface marker (anti-CD4 or anti-CD8) dot plots.

Five-color flow cytometry was performed to identify DC subsets in PBMC. Determination of gates was based on fluorescence minus one (FMO) controls for directly labeled antibodies and no first antibody controls when fluorescent secondary antibodies were utilized. Numbers represent percentage of cells in from parent population.

Mouse anti Bovine MHC Class II Monomorphic antibody, clone IL-A21 recognizes a monomorphic epitope within the bovine MHC II cell surface antigen. Clone IL-A21 is reported to react with an epitope which is common to both BoLA DR and DQ  (Howard et al.1997).

Expression of MHC II molecules have been demonstrated on bovine B cells, activated T cells, alveolar macrophages, monocytes and mammary and bronchial epithelial cells.

Clone IL-A21 is reported to inhibit T cell proliferation following FMDV infection (Collen et al. 1991).
