Many specific therapeutic antibody drugs have been developed for different indications. In drug development, it has been found that the antibody isotype framework can not only affect the physical and chemical properties of therapeutic antibodies, but also influence the activity and therapeutic effect. As a result, IgG isotype selection should be considered carefully in antibody drug development strategies. Because of the unique biological characteristics, IgG4 isotype has been used in some therapeutic antibodies for which effector functions are not desired. In order to provide new ideas for the development of antibody drugs, the research and application progress of IgG4 isotype in therapeutic antibody drug development has been reviewed.

Objective To explore the role of CGRP and progesterone along with it on the etiopathology of PIH. Methods 8 specimens of umbilical vein endothelial cells from women with PIH were cultured. Four groups were divided when cultured cells were confluent: the sera of normal pregnancy women (group 1), the sera of women with PIH (group2), the mixture of the sera of women with PIH and the injection of progesterone (group3), and the same amount of media (group 4). The cultured cell were added respectively into the four different kinds of media. After 24h of incubation, the concentration of endothelin (ET) and CGRP in media were measured by radioimmunoassay. Results 1. Comparing with group1, the concentration of CGRP in group 2 decreased and ET increased significantly. Statistic difference of ET/CGRP was found between the two groups. 2. Comparing with group 1, the concentration of CGRP in group 3 was unchanged and ET increased obviously. No difference of ET/CGRP was shown between them. 3. Comparing with group 3, in group 2, the concentration of CGRP decreased obviously and that of ET unchanged. Significant difference of ET/CGRP was found. Conclusions Progesterone, along with CGRP, might delay the onset and progressing of PIH.
