Abstract
- Phosphorylation of signal transducer and activator of transcription 3 (STAT3) is essential for cell survival, proliferation and differentiation. STAT3 phosphorylation results from signaling by cytokines and growth factors, and constitutive STAT3 activity is characteristic of a number of human malignancies, including Cutaneous T Cell Lymphoma (CTCL). Furthermore, we now know that STAT3 is also required for the initiation and maintenance of the Th17 differentiation program. Th17 cells are a subset of CD4 T helper cells that have been implicated in chronic inflammatory conditions like rheumatoid arthritis and psoriasis. Mycosis fungoides (MF) and the leukemic variant of this disease, Sezary syndrome (SS), are the most frequently encountered forms of CTCL and in both of these diseases, the cell of origin – as far as the type of Teffector cell involved, has not been defined. Recent results from our laboratory and that of our colleagues have lead us to believe that Th17 cells may either be the cells of origin in CTCL or may act as critical mediators of chronic inflammation that creates a favorable environment for tumor growth in the context of this malignancy.
