Type II natural killer T (NKT) cells in cancer immunity are typically associated with suppression of tumor immunosurveillance through secretion of IL-13. We previously demonstrated that CpG oligonucleotide therapy activated Type II NKT cells to produce T helper type 1 (Th1) rather than T helper type 2 (Th2) cytokines. This cytokine skewing may manifest in Type II NKT cell antitumor properties i...
The aetiology of chronic sinusitis is still poorly understood. The expression of T-helper 1 (Th1) and T-helper 2 (Th2) cell markers, interleukin (IL)-12 receptor beta2 subunit (IL-12Rbeta2) messenger ribonucleic acid (mRNA) and CD30, respectively, were investigated in the paranasal sinus mucosa of patients with chronic sinusitis in an attempt to elucidate the involvement of Th1 and Th2 cells in...
Regulatory T (Treg) cells are considered to inhibit the development of both type 1 (Th1) and type 2 helper T (Th2) cells. However, it is recently reported that there are reduced numbers of Treg cells in patients with allergic diseases as compared with individuals who have high levels of serum immunoglobulin E and blood eosinophils but are asymptomatic. Therefore, Treg cells may suppress the ons...
We have previously shown that CD4(+) T cell-mediated allergic inflammation is diminished in signal transducer and activator of transcription (Stat)5a-deficient (Stat5a(-/-)) mice. To determine whether Stat5a regulates T helper cell differentiation, we studied T helper (Th)1 and Th2 cell differentiation of Stat5a(-/-)CD4(+) T cells at single-cell levels. First, Th2 cell differentiation from anti...
BACKGROUND Although in vitro IL-4 directs CD4 T cells to produce T helper 2 (Th2)-cytokines, these cytokines can be induced in vivo in the absence of IL-4-signalling. Thus, mechanism(s), different from the in vitro pathway for Th2-induction, contribute to in vivo Th2-differentiation. The pathway for in vivo IL-4-independent Th2-differentiation has yet to be characterized. FINDINGS Helios (ikz...
T helper 2 (Th2) cells play a central role in the progression of many diseases such as allergic airway inflammation, autoimmune diseases, and infections caused by intracellular pathogens. Consequently, animals such as BALB/c mice, which exhibit a propensity for generating Th2 responses, are susceptible to allergic airway inflammation, type-II autoimmune diseases, and various infections induced ...
Type 1 and type 2 cloned T helper (Th) cells are believed to require different antigen-presenting cell (APC)-derived costimuli for proliferation. In the case of Th1-cloned T cells, CD28 signaling costimulates production of autocrine interleukin 2 (IL-2). Th2 cells produce their autocrine growth factor, IL-4, without costimulation, but require APC-derived costimuli, or IL-1, to respond to IL-4. ...
