Functional characterization of three mouse formyl peptide receptors.

The evolutionary relationship and functional correlation between human formyl peptide receptors (FPRs) and their mouse counterparts remain incompletely understood. We examined three members of the mouse formyl peptide receptor subfamily (mFprs) and found that they differ in agonist preference and cellular distributions. When stably expressed in transfected rat basophilic leukemia (RBL-2H3) cells, mFpr1 was readily activated by N-formylated peptides derived from Listeria monocytogenes (fMIVTLF), Staphylococcus aureus (fMIFL), and mitochondria (fMMYALF).

[Differences of concept and entity of xiao-named herb between Shennong's Herbal Classic and Song-edition Treatise on Febrile Disease and Golden Chamber].

There are significant differences of the XIAO-named herb between Shennong's Herbal Classic and the Song-edition Treatise on Febrile Disease and Synopsis of the Golden Chamber. The reasons are: (1) With the development of history, differentiation of herb category and effect kept changing from the Han Dynasty to the Song Dynasty, which led to the differences in concept and entity of herbs in different periods. (2) Lin Yi of the Song Dynasty may have redefined some herb's names according to the current situation when he revised Zhang Zhongjing's works.
