The peripheral CD4+ T cell pool includes multiple effector and memory T cell subsets that arise through antigen-driven
expansion and differentiation of naïve T cells. The early response of naïve CD4+ T cells to antigenic stimulation is characterized
by high level proliferation and a limited cytokine repertoire. Further differentiation yields cells with a more diverse potential for
cytokine expression. Depending upon the balance of local cytokines, costimulatory molecules, antigen levels, and genetic
factors, Type-1 T helper (Th1), Th2, and Th17 effector and/or memory cells are generated by immune responses.

Functionally-polarized CD4+ T cell subsets have been identified based on their distinctive patterns of cytokine secretion. As a
signature cytokine, Th1 cells selectively produce large amounts of interferon-gamma (IFN-γ). Th2 cells selectively produce IL-4,
and Th17 express high levels of IL-17A. Through secretion of IFN-γ and other effector molecules, Th1 cells activate
macrophages, natural killer (NK) cells, and CD8+ T cells and are responsible for cell-mediated immunity. Th1 cells provide
protection against intracellular bacteria, fungi, protozoa and viruses and are involved in some autoimmune responses. IL-4
produced by Th2 cells is particularly strong in driving B cells to generate IgE-secreting cells. IgE plays a role in basophil/mast
cell mediated immune reactions. Th2 cells mediate protection against extracellular parasites but may also cause harmful allergic
responsiveness to develop. Through the secretion of IL-17A and other factors, Th17 cells recruit and activate neutrophils and
mediate immune responses against extracellular bacteria and fungi. Th17 cells are also implicated in autoimmune responses. In
addition to these types of T helper Investigators should note that the appearance of BD GolgiStop™ Protein Transport Inhibitor may range in color from clear
(colorless) to light yellow.

Preparation and Storage
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.
Irritating to eyes and skin. Do not breathe vapor. In case of contact with eyes, rinse immediay with plenty of water and seek medical
advice. Wear suitable protective clothing.
The antibody was conjugated to APC under optimum conditions, and unconjugated antibody and free APC were removed.
The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.
The antibody was conjugated with PerCP-Cy5.5 under optimum conditions, and unconjugated antibody and free PerCP-Cy5.5 were
removed. Storage of PerCP-Cy5.5 conjugates in unoptimized diluent is not recommended and may result in loss of signal intensity.
The antibody was conjugated with FITC under optimum conditions, and unreacted FITC was removed.

A. Stimulation of the Cells
Various in vitro methods have been reported for polarization or stimulation of T helper cells subsets of which PMA (Phorbol ester) plus
Ionomycin (Calcium Ionophore) has been particularly useful for quickly inducing and characterizing polyclonal cytokine-producing cells. For this
kit we recommend the stimulation of normal PBMCs at a concentration of 1-10 million cells per ml in media for 5 hours with PMA/Ionomycin (at
50 ng/ml and 1 μg/ml respectively) in the presence of BD GolgiStop™ Protein Transport Inhibitor (provided in the kit or Cat #554724). Add 4 μl
of BD GolgiStop™ for every 6 ml of cell culture and mix thoroughly. It is recommended that BD GolgiStop™ not be kept in cell culture for
longer than 12 hours.
Note: Kinetic studies need to be performed to determine the optimal incubation time for each experimental system. Depending on the donor, frequencies of cytokine
producing cells derived from activation of PBMC can vary widely for a specific cytokine. In particular, the number of IL-17 producing cells can be very low or even
negligible on PMA/Ionomycin stimulated PBMC. In these cases, Th17 polarization cultures should be considered. For specifics on polarization of Th17 cells please refer
to the references.
