Macrophages in malignant pleural effusions – alternatively activated tumor associated macrophages
Pleural macrophages are involved in local defense mechanisms against environmental pollution, bacteria and cancer. Their main function encompasses phagocytosis of degenerated mesothelial cells. In human pleural effusions macrophages represent more than half of all cells. A model of polarized macrophage activation (M1 and M2) was proposed, which defines a functionally different macrophage popula...
متن کاملEosinophils sustain adipose alternatively activated macrophages associated with glucose homeostasis.
Eosinophils are associated with helminth immunity and allergy, often in conjunction with alternatively activated macrophages (AAMs). Adipose tissue AAMs are necessary to maintain glucose homeostasis and are induced by the cytokine interleukin-4 (IL-4). Here, we show that eosinophils are the major IL-4-expressing cells in white adipose tissues of mice, and, in their absence, AAMs are greatly att...
متن کاملAlternatively activated macrophages in infection and autoimmunity.
Macrophages are innate immune cells that play an important role in activation of the immune response and wound healing. Pathogens that require T helper-type 2 (Th2) responses for effective clearance, such as parasitic worms, are strong inducers of alternatively activated or M2 macrophages. However, infections such as bacteria and viruses that require Th1-type responses may induce M2 as a strate...
متن کامل[Alternatively activated macrophages in helminth infections].
Macrophages not only initiate and modulate immune responses, but also are the final effector cells. Recent studies suggested that macrophages conventionally associated with IFN-gamma dominant Th1-type responses and also playing an essential role in the Th2-type inflammatory response, exhibit a quite different activation from the classically activated macrophages (CAM Phi) stimulated during Th1-...
متن کاملCCL17 and IL-10 as effectors that enable alternatively activated macrophages to inhibit the generation of classically activated macrophages.
Classically activated macrophages (CAMphi) have been described as a major effector cell on the host's innate immunities. However, CAMphi are not generated in immunocompromised hosts whose alternatively activated macrophages (AAMphi) predominate. In this study, the mechanism by which AAMphi suppress the ability of resident macrophages (RMphi) to generate CAMphi was investigated. AAMphi were isol...
