Background: It has been proposed that a dysregulation in the balance between type Th1 (IL-2, IFN-gamma) and type Th2 (IL-4, IL-10) cytokines may be implicated in the development of cancer.
Methods: We determined the expression of IL-2, IL-4, IL-10, and IFN-gamma in CD4 and CD8 lymphocytes by flow cytometry in 12 patients with prostate cancer and in 7 healthy subjects. In addition to the basal expression of these cytokines, their expression was also determined, following stimulation of lymphocytes with PMA (phorbol 12-mystirate 13 acetate) and ionomycin.
Results: The basal expression of cytokines was scarce, while following stimulation this increased markedly. On the other hand, there was a dysregulation in the balance between Th1 and Th2 lymphocytes in patients with prostate cancer. To this effect, in relation to healthy subjects, we observed an increase in IL-10 expression and a decrease in IL-2 expression.
Conclusions: The disequilibrium observed in the balance between type Th1 and type Th2 cytokines may be implicated in the evolution of neoplastic disease.

Effects of Th1/Th2 on tumor progression
Naive T cells become Th1 cells or Th2 cells, following the stimulation by different factors. In Th1 immunity, cells produce pro-inflammatory cytokines, such as interleukin-2 (IL2), interferon-gamma (IFN-γ), and tumor necrosis factor-beta (TNF-β). In Th2 immunity, cells produce antiinflammatory cytokines, such as IL-4, IL-5, IL-6, IL-10, and IL-13. In normal circumstances, Th1 immunity and Th2 immunity approach a balance. But, the presence of tumor cells disrupts this balance. This occuring increased Th2 immunity and decreased Th1 immunity, because of down-regulation of adaptive immunity. This eventually leads to tumor progression. However, if Th1 immunity becomes predominant, this stimulation of immunity can lead to tumor regression. In prostate cancer patients IL-2 was low (Th1) and IL-10 high (Th2).
Are You Th1 or Th2 Dominant?
The following have been associated with Th2 dominance in studies:
-- Cancers
-- Food allergies
-- Seasonal allergies
-- Airway constriction
-- Asthma
-- Nasal drip
-- Mucus
-- Eczema (Dermatitis)
-- Hay fever (Allergic rhinitis)
-- Increased stomach acidity or GERD
-- Histamine intolerance
-- Hives (Urticaria)
-- Chronic Fatigue Syndrome
-- Autism
-- Uveitis
-- Grave’s disease
-- Sjogren’s
-- Oral Lichen Planus
