Among adhesion molecules evidencedin leprosy, it is possible to highlight the intercellular adhesion molecule-1 (ICAM-1) andits ligand, lymphocyte function-associated antigen-1 (LFA-1) (Sullivan et al. 1991, Rieckmann et al.1996), E-selectin (Rieckmann et al. 1996),as well as vascular cell adhesion molecule 1 (VCAM-1) (Martinuzzo et al. 2002). This evidence concerns the gene VCAM1 and leprosy.
