(34), observed that after extensive burn injuries, considerable amounts of pro-inflammatory cytokines are Alisol B 23-acetate released into circulation. These pro-inflammatory cytokines, such as IFN-, TNF-, IL-1, IL-4, IL-6, IL-13, IL-17, cause increased intestinal permeability, besides affecting the Alisol B 23-acetate intestinal barrier. Activated T cells proliferate and differentiate into effector or memory T cells. After activation, CD4+ T-cell subset become engaged in mediating the adaptive immune response by producing T helper type 1 (Th1) cytokines, pro-inflammatory cytokines (IL-2, IFN-, TNF-) involved in the cell-mediated immune response. CD4+ T-cells also secrete T helper type 2 (Th2) cytokines and anti-inflammatory cytokines (IL-4, IL-10, IL-13) which modulate the humoral immune response. It has previously been established that this T cells can self-regulate their activity through the synthesis of IL-10 and the transforming growth factor- (TGF-), which inhibit T cell proliferation and cytokine production, either directly or via other cytokines (35-37). Some studies have reported correlations between the serum concentrations of some cytokines (IL-6, IL-8, IL-10) or MCP-1 with the size of the lesions at 24 or 48 h after the burn. It was also found that the serum concentrations of IL-10, even have a prognostic value, when measured in hospitalized patients, but also at 24-48 h after the burn (38). In animal studies, high levels of IL-10 were evidenced even 84 days after the burns occurred (39). Another study direction consists of the inhibition of the immune defense activation by modulation of the activity of the complement system. nonspecific immune response activation occurs through the involvement of the C3 and C5 complement fractions, which increase the ability of defense by direct and indirect action on microbial brokers and facilitate wound healing (40-43). Under burn conditions, systemic upregulation of the complement cascade and the C-reactive protein Alisol B 23-acetate occurs, which increases the risk of generalized inflammation and delays wound healing (44-46). Experimental investigations have shown favorable effects of using a C1 fraction inhibitor, to limit tissue destruction in case of experimentally-induced burns in pigs (47). Other researches revealed that the treatment with an inhibitor of the C4 fraction prevented the development of hypertrophic scars in a burn model in mice (48). Stress that is the result of burn injury causes disruptions of the immune system as a consequence of suppressing the cellular immunity (Th1 cell activity, which mediates pro-inflammatory processes) and stimulating the Mouse monoclonal to CRTC3 humoral Alisol B 23-acetate immunity, involved in the anti-inflammatory response (35,49,50). Recent research has shown that this granulocyte-colony stimulating factor (G-CSF), with stimulatory effects on defense capacity, is an essential element in modulating the immune response, with favorable effects in the evolution of burn wound healing (51). Clinical investigations evidenced that this administration of a recombinant glycoprotein of the granulocyte-macrophage colony-stimulating factor 2 (GM-CSF2), a drug approved for use by the Food and Drug Administration (FDA), has been associated with an increased percentage of healing and a higher survival rate in sufferers with septic uses up (44,52). It had been suggested that the consequences of GM-CSF may be the aftereffect of the recovery of macrophage and monocyte dysfunctions, aswell as the boost of.
