Cytokine production pathway in the elderly.
1996
It is well known that aging is associated with various alterations in lymphoid cell functions, particularly with a progressive decline in immune responsiveness to exogenous antigens and increasing incidence of autoimmune phenomena. Many studies have been focused on the mechanisms of the immunologic features of aging. this review describes our results of studies performed to determine the influence of age on the capacity to produce interleukin-2 (IL-2), interferon-gamma (IFN-gamma), interleukin-4 (IL-4), interleukin-t (IL-5), interleukin-6 (IL-6) and tumor necrosis factor (TNF). Mitogen-stimulated cultures of mononuclear cells (MNC) from human beings were assessed for cytokine-producing capa…
Serum levels of interleukin-18 and s-ICAM-1 in patients affected by psoriasis: preliminary considerations.
2003
Objective To find new aspects of the systemic involvement of the Immune System in psoriasis, we determined serum levels of interleukin-18 (IL-18) (Th1-inducing factor cytokine), CD30 (Th2 marker) and sICAM-1 (adhesion molecule). In addition we evaluated the correlation between these molecules and psoriasis area and severity index (PASI). Background Psoriasis is associated to an overexpression of Th1 cytokines and a relative underexpression of Th2 cytokines. IL-18 plays an important role in inducing Th1 response because it is a potent inductor of synthesis of IFN-γ, TNF and other mediators. The two major sources of IL-18 are monocytes and macrophages but also human keratinocytes constitutive…
