Local Activation of the Alternative Pathway of Complement System in Mycotic Keratitis Patient Tear

Frontiers in Cellular and Infection Microbiology, 2020
Aspergillus flavus and Fusarium solani are the predominant causative agents of mycotic keratitis in the tropical part of the world. Tear proteins play a major role in the innate immune response against these fungal infections as has been shown by the ...

IMMUNOLOGICAL STUDIES OF THE 11S PROTEIN COMPONENT OF THE HUMAN COMPLEMENT SYSTEM [PDF]

The Journal of Experimental Medicine, 1964
Rabbit anticryoprotein and anticomplement antisera recognized a heat-labile antigen in normal human serum. This antigen best fitted the previously described US protein because of its presence in fresh human serum, euglobulin, and purified 11S preparations and its absence in heated serum, R11S, and pseudoglobulin preparations. The 11S hemolytic activity
