The coagulation system is a proteolytic cascade of plasma enzymes that triggers blood clotting when blood vessels are damaged.
surface immunoglobulin
Biology; Immunology
The membrane-bound immunoglobulin that acts as the antigen receptor on B cells is often known as surface immunoglobulin (sIg).
toxoids
Biology; Immunology
Inactivated toxins called toxoids are no longer toxic but retain their immunogenicity so that they can be used for immunization.

Biology; Immunology
Leukocyte is a general term for a white blood cell. Leukocytes include lymphocytes, polymorphonuclear leukocytes, and monocytes.
allergic conjunctivitis
Biology; Immunology
The lining of the eye, called the conjunctiva, manifests allergic conjunctivitis in sensitized individuals exposed to allergens.
major basic protein,
Biology; Immunology
Eosinophils can be triggered to release their major basic protein, which can then act on mast cells to cause their degranulation.
central tolerance
Biology; Immunology
Central tolerance is tolerance that is established in lymphocytes developing in central lymphoid organs. Cf. peripheral tolerance.
