The three selectins (P-selectin, L-selectin, and E-selectin) have related and sometimes overlapping functions in cell adhesion and mediate some of the best characterized glycan-dependent cell adhesion events. Of these three C-type lectins, the target ligand of P-selectin, P-selectin glycoprotein ligand 1 (PSGL-1), is the best understood. Thus, P-selectin is used here to represent all three selectins.


CFG Participating Investigators contributing to the understanding of this paradigm

Selectin research was already at a relatively mature stage when the CFG began. Early PI work included structural studies, extensive analysis of leukocyte adhesion to endothelia in vivo, and characterization of knockout mice to demonstrate physiological function. In addition to submitting samples for glycan array analysis, PIs have been involved in analyzing selectin expression under different conditions, including in knockout mice lacking enzymes for making target ligands.

  • PIs working on P-selectin include: Hans-Peter Altevogt, Bruce Bochner, Pi-Wan Cheng, Richard Cummings, Robert Fuhlbrigge, Minoru Fukuda, Geoff Kansas, Klaus Ley, John Lowe, Rodger McEver, Steve Rosen, Ron Schnaar, Karen Snapp, Lloyd Stoolman, Martin Wild, Hermann Ziltener
  • Non-PIs who have used CFG resources to study P-selectin include: Roland Contreras, Leonard Seymour

CFG resources used in investigations

The best examples of CFG contributions to this paradigm are described below, with links to specific data sets. For a complete list of CFG data and resources relating to this paradigm, see the CFG database search results for P-selectin.

Glycan profiling

The glycans on the main target for P-selectin, P-selectin glycoprotein ligand 1 (PSGL-1), were analyzed.

Glycogene microarray

Regulation of P-selectin expression was analyzed under multiple conditions.

Knockout mouse lines

The phenotype of PSGL-1 knockout mice was analyzed by the CFG.

Glycan array

The comparative binding specificities of human and mouse selectins were analyzed.

Related GBPs
