Mast cells, cytokines, inflammation, hypersensitivity, tumours In this review, mast cells distribution and function in physiological conditions and in different human pathologies are analyzed. Their participation in tumor proggression is contradictory and requires further studies. Nevertheless, mast cells are associated with a number of pathologies and reactions including inflammatory process, type I hypersensitivity reaction, tissue remodeling and angiogenesis. The most well known role of mast cells is their participation in host defenses against parasitc infections. All these molecules play a key role in numerous physiological and pathological processes. These cells can be activated by several immunological or non-immunological stimuli, releasing a wide range of biological mediators including histamine, proteases, cytokines, growth factors and arachidonic acid metabolites.

Mast cells populate most tissues, but are found in highest number in the skin and mucosal surfaces located usually in the periphery of blood and lymph vessels in the connective tissue. Mastocitos, citoquinas, inflamaciГіn, hipersensibilidad, cГЎncer En esta revisiГіn se analiza el origen, la distribuciГіn y las funciones de los mastocitos en condiciones fisiolГіgicas y en distintas enfermedades humanas. Intervienen en las reacciones de hipersensibilidad tipo I y tienen un papel contradictorio en la progresiГіn tumoral. Median la respuesta inflamatoria, la remodelaciГіn de los tejidos y la angiogГ©nesis. La funciГіn mejor conocida de los mastocitos es la defensa contra infestaciones parasitarias sin embargo, son importantes en la defensa del huГ©sped a travГ©s de su participaciГіn en la inmunidad innata y adaptativa. Estas molГ©culas juegan un importante papel en numerosos procesos fisiolГіgicos y patolГіgicos. Pueden ser activadas por diversos estГmulos de origen inmunitario o no inmunitario, liberando un amplio espectro de mediadores que incluyen histamina, proteasas, citoquinas, factores de crecimiento y metabolitos del ГЎcido araquidГіnico. Los mastocitos o cГ©lulas cebadas son cГ©lulas que se hallan ampliamente distribuidas en todos los tejidos, principalmente en la piel y en las superficies mucosas cerca de los vasos sanguГneos y linfГЎticos.
