Mast cells as novel mediators of reproductive processes
نویسندگان
چکیده
The relationship between mast cells (MCs) and pregnancy is a controversially discussed topic. The presence and quantitative distribution of MCs in the reproductive tract was confirmed in different species. A phase-dependent oscillation of MCs during the hormonal regulated estrous cycle was suggested and on this basis, MCs were assumed to play a positive role in implantation because of their ability to secrete histamine. At later pregnancy stages, they were proposed to have rather a negative role, as their exacerbated activation is associated with pre-term delivery. The present review is intended to provide an overview about uterine MCs that bring to light their unexpected relevance for reproductive processes.

Mast cells are a heterogeneous population of granulocytic cells in the immune system. Mast cell granules contain numerous mediators, including neurotransmitters, cytokines, chemokines and lipid-derived factors. In addition to their well-known role in immune inflammation, the presence of mast cells in the meninges and perivascular space in the central nervous system points to their role in brain...

Mast cells are important in the development of allergic and anaphylactic reactions, but also in acquired and innate immunity. There is also increasing evidence that mast cells participate in inflammatory diseases, where they can be activated by non-allergic triggers, such as neuropeptides and cytokines, often having synergistic effects as in the case of substance P (SP) and IL-33. Secretion of ...
