A summary of mast cells, large cells rich in granules found in connective tissues, particularly submucosa and dermis. Their granules contain histamine and other bioactive molecules, and these cells are involved in parasite defense and allergic reactions.
Uma célula granular grande encontrada em tecidos conjuntivos por todo o corpo, mais abundantemente nos tecidos submucosos e na derme. Os grânulos armazenam moléculas bioativas, incluindo a amina vasoativa histamina, que são liberadas na ativação dos mastócitos. Acredita-se que os mastócitos estejam envolvidos em defesas contra parasitas e desempenham um papel crucial nas reações alérgicas.
