Role of macrophages in the endocrine system

Rehman, Abdul, Pacher, Pál, Haskó, György·2021·Trends in Endocrinology & Metabolism

Abstract

Macrophages are cells of the innate immune system that play myriad roles in the body. Macrophages are known to reside in endocrine glands, and a body of evidence now suggests that these cells interact closely with endocrine cells. Immune-endocrine interactions are important in the development of endocrine glands and their functioning during physiological states, and also become key players in pathophysiological states. Through gene expression profiling, diverse subpopulations of tissue macrophages have been discovered within endocrine organs; this has important implications for disease pathogenesis and potential pharmacotherapy. The molecular basis for the crosstalk between macrophages and endocrine cells is being unraveled, and allows the identification of multiple points for pharmacologic intervention. Macrophages in adipose tissue and pancreatic islets are key players in the process of metaflammation (metabolic inflammation) that underlies the development of insulin resistance, metabolic syndrome, diabetes mellitus, and non-alcoholic fatty liver disease. In the ovary, they play important roles in ovarian folliculogenesis and ovulation, whereas in the male reproductive tract they regulate spermatogenesis through the regulation of steroidogenesis by Leydig cells. We summarize the diverse roles played by macrophages in the endocrine system and identify potential targets for pharmacotherapy in endocrine disorders.

  • Resident macrophages and T-lymphocyte immune cells perpetuate the inflammatory situation in adipose tissue.

    “It is namely resident macrophages and T-lymphocyte immune cells that perpetuate the inflammatory situation in adipose tissue [68], and dietary saturated fatty acids can be a direct source of metabolic stress that can promote inflammation by increasing TLR4 signaling.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
