Th1 Polarization of Mouse CD4+ Cells

Introduction:

Th1 cells are a distinct lineage of CD4+ effector T cells that are characterized by their production of IL-2, IFN-γ and Lymphotoxin (LT) after activation in the presence of IL-12. IL-12 drives CD4+ T cell differentiation to the Th1 lineage through the sequential involvement of cell-extrinsic and cell-intrinsic factors, including signal transducer and transcription activator 1 (STAT1), the transcription factor T-bet, IL-12 and STAT4. Th1 cells are characterized by the expression of the cell surface markers CCR5, CXCR3, cytokine receptors IL-12Rβ2, and IL-18Rα. They are mainly involved in the cellular immune response and host defense against intracellular pathogens. They are also found to be associated with autoimmune diseases, including rheumatoid arthritis, multiple sclerosis, inflammatory bowel disease, type 1 diabetes, organ-specific autoimmune disorders, Crohn's disease, Helicobacter pylori-induced peptic ulcer, acute kidney allograft rejection, and unexplained recurrent abortions.

Isolation of CD4+ Cells From Lymph Nodes:

 

  1. Harvest lymph nodes (superficial cervical, mandibular, axillary, inguinal, and mesenteric) from mice.
  2. Tease lymph nodes through a sterile 70-µm nylon cell strainer to obtain single-cell suspensions in complete RPMI containing 10% FCS (complete medium).
  3. Resuspend cells in complete medium and use your favorite method to isolate CD4+ cells, such as the MojoSort™ Mouse CD4 T Cell Isolation Kit.

Th2 Polarization of Mouse CD4+ T Cells

Introduction:

Th2 cells are a distinct lineage of CD4effector T cells that secrete IL-4, IL-5, IL-9 and IL-13 after activation in the presence of IL-4 and either IL-2, IL-7, or Thymic Stromal Lymphopoietin (TSLP). IL-4 drives CD4+ T cells by engaging the IL-4R, thereby activating STAT6 and the transcription factor GATA-3. Th2 cells are characterized by the expression of the cell surface receptors, ST2/IL-1 R4, CXCR4, CCR3, CCR4, and CCR8. These cells are responsible for strong antibody production, eosinophil activation, and inhibition of several macrophage functions. They mediate development and maintenance of many allergic diseases such as allergic airway inflammation (allergic asthma) or atopic dermatitis, Omenn's syndrome, reduced protection against some intracellular pathogens, transplantation tolerance, chronic graft vs host disease, atopic disorders, and some systemic autoimmune diseases.

Treg Polarization of Mouse CD4+ Cells

Introduction:


Regulatory T cells (Tregs) are a subpopulation of T cells dedicated to maintaining self-tolerance that express the forkhead family transcription factor FOXP3 (forkhead box p3). FOXP3+ Tregs mainly comprise naturally occurring Tregs (nTregs) and adaptive or induced Tregs (aTreg or iTreg). nTreg cells arise in the thymus following ligation of high-affinity T cell receptors (TCRs). These cells express the high-affinity form of the interleukin-2 (IL-2) receptor but depend on exogenous IL-2 to maintain FOXP3 expression. iTreg cells differentiate from mature, naïve CD4+ T cells in peripheral lymphoid organs and other tissue upon cellular activation in the presence of TGF-β1. In vitro, a combination of IL-2 and anti-CD3/CD28 antibodies sufficiently expand Tregs. Expansion of Tregs can be further enhanced by artificial antigen presenting cells over-expressing CD86 and FcR. Treg cells play an indispensable role in maintaining immunological unresponsiveness to self-antigens and in suppressing excessive immune responses deleterious to the host. Tregs exert their function by secretion of immunosuppressive soluble factors such as IL-9, IL-10 and TGF-β and cell-mediated regulation via the high affinity TCR, cytolytic activity, and other co-stimulatory molecules such as GITR and CTLA-4.

Th17 Polarization of Mouse CD4+ Cells

Introduction:

 

T helper 17 (Th17) cells are a subset of CD4+ T helper cells characterized by their production of IL-17, particularly IL-17A and IL-17F. They are involved in autoimmune diseases such as multiple sclerosis, psoriasis, autoimmune uveitis, rheumatoid arthritis, and juvenile diabetes, but are also important in anti-microbial defenses at epithelial/mucosal barriers, particularly against Candida and Staphylococcus. In addition to IL-17, Th17 cells also produce IL-21 and IL-22 that contribute to pro-inflammatory responses. The transcription factors RORα and RORγt have been identified as important factors in the differentiation of these cells. Th17 cells can be induced in vitro by a variety of cytokines including TGF-β, IL-6, IL-21 and IL-23. Here we provide an effective protocol for the generation of mouse IL-17 producing cells in vitro.

Th9 Polarization of Mouse CD4+ Cells

Introduction:

 

Th9 cells are a subpopulation of T helper cells involved in allergic diseases and resistance against intestinal nematodes. Unlike Treg cells, Th9 cells are not suppressive, as they can promote T cell proliferation along with other effector T cells. Th9 cells do not express any well-defined transcription factors like T-bet, GATA3, RORγt, or FOXP3, clearly differentiating them from Th1, Th2, Th17 and FOXP3+ iTreg populations. TGF-β reprograms Th2 T helper cells to lose their characteristic profile of IL-4, IL-5 and IL-13 secretion and switch to IL-9 secretion. Differentiation of Th9 cells can be obtained by a combination of TGF-β and IL-4. In addition, the neutralization of IFN-γ is critical to drive the pathway to Th9 cells. Here we provide an effective protocol for the generation of mouse Th9 cells in vitro.

Data:

Naïve BALB/c mouse CD4+ T cells were polarized with 5 µg/ml plate-bound anti-mouse CD3ε (clone 145-2C11 , Cat. No. 100339), 5 µg/ml soluble anti-mouse CD28 (clone 37.51, Cat. No. 102115), 20 ng/ml IL-2 (Cat. No. 575402), 10 ng/ml IL-4 (Cat. No. 574302), 10 ng/ml TGF-β1 (Cat. No. 580702), and 10 µg/ml anti-mouse IFN-γ (clone XMG1.2, Cat. No. 505833) for 3 days. On day 3, the cells were re-stimulated with 500 ng/ml PMA/ionomycin in the presence of monensin for 6 hours. Then the cells were harvested and surface stained with CD4 PE (clone GK1.5, Cat. No. 100408), intracellular stained with IL-9 APC (clone RM9A4, Cat. No. 514105) along with IFN-γ Alexa Fluor® 488 (clone XMG1.2, Cat. No. 505813), IL-4 Alexa Fluor® 488 (clone 11B11, Cat. No. 504109), or IL-17 Alexa Fluor® 488 (clone TC11-18H10.1, Cat. No. 506910) after fixation and permeabilization.
