Regulation of cathepsin E expression during human B cell differentiation in vitro
European Journal of Immunology
|August 1, 1996
Abstract:
Cathepsin E is an aspartic proteinase which has been implicated in antigen processing in the class II major histocompatibility complex pathway. In this study we show that cathepsin E, measured at both the protein and message level, is up-regulated late in human B cell activation. The implications of this observation in terms of cathepsin E function are discussed.

Cell Specific Gene Expression
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...
Cadherins in Tissue Organization
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.
