Abstract

The C-type lectins DC-SIGN and DC-SIGNR bind and transmit HIV-1 depending on the tetramer formed by "neck" region and carbohydrate recognition domain (CRD). Recent studies indicated polymorphisms in neck region of DC-SIGNR were more frequent and associated with susceptibility to HIV-1 infection, whereas no similar trends were observed on DC-SIGN for rare variations of DC-SIGN among the researched subjects in those studies. In our present study, we found 9 genotype variations of DC-SIGN neck region among HIV infected Germans and 3 variations among HIV infected Chinese, respectively. Comparison of those variations between Chinese and Germans reveals strong ethnic discrepancies, and no significant evidence indicates those variations have resistance to susceptibility to HIV-1 infection.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function. Discover the latest research on adhesion molecule and their role in health and disease here.
