Immunoreactions Involving Platelets
Theoretical equations have been derived, using the methods of statistical mechanics, for associations between platelets, antibody, quinidine, and complement, based on a model of an immunoreaction described in the preceding paper of this series. The two cases considered (i.e. the possibilities that quinidine can attach first to antibody or platelets) lead to the same final equations. The compari...
متن کاملImmunoreactions Involving Platelets
Quantitative aspects of platelet agglutination and inhibition of clot retraction by the antibody of quinidine purpura were described. The reactions appeared to depend on formation of types of antibody-quinidine-platelet complexes which could fix complement but complement was not necessary for these reactions. Complement fixation was at least 10 times more sensitive than platelet agglutination o...
متن کاملThe source of HLA molecules on platelets: Does platelets adsorb soluble HLA molecules from their environment?
Background: The origin and function of human leukocyte antigen (HLA) class I molecules on platelets are still highly arguable. Given the differences in the results of the previous studies in this regard, the lack of research in recent years, and the clinical importance of HLA class I molecules, the absorption capacity of platelets for soluble HLA class I molecules was studied in this investigat...
متن کاملAlboaggregin A activates platelets by a mechanism involving glycoprotein VI as well as glycoprotein Ib.
The snake venom C-type lectin alboaggregin A (or 50-kd alboaggregin) from Trimeresurus albolabris was previously shown to be a platelet glycoprotein (GP) Ib agonist. However, investigations of the signal transduction induced in platelets showed patterns of tyrosine phosphorylation that were different from those of other GPIb agonists and suggested the presence of an additional receptor. In this...
متن کاملHeparin and cancer revisited: mechanistic connections involving platelets, P-selectin, carcinoma mucins, and tumor metastasis.
Independent studies indicate that expression of sialylated fucosylated mucins by human carcinomas portends a poor prognosis because of enhanced metastatic spread of tumor cells, that carcinoma metastasis in mice is facilitated by formation of tumor cell complexes with blood platelets, and that metastasis can be attenuated by a background of P-selectin deficiency or by treatment with heparin. Th...
