Abstract

CD40/CD40L signaling is known to play an important role in immune response. The proteins are expressed in a variety of cell types and ligation causes cells to produce inflammatory cytokines and cellular adhesion molecules. These processes are implicated in the development and progression of atherosclerosis. Animal models demonstrate that interruption of CD40/CD40L signaling produces a more fibrous and stable atherosclerotic lesion. We investigated the role of genetic variation in CD40 and CD40L genes in subclinical atherosclerosis assessed by coronary artery calcification (CAC) and carotid intima-media thickness in 620 individuals from 230 families in the DHS. Two single nucleotide polymorphisms in the CD40 gene (rs1535045 and rs3765459) were significantly associated with decreased CAC (P < or = .02) in this population. CD40L single nucleotide polymorphisms were not significantly associated. In addition, no associations with carotid intima-media thickness, carotid artery calcification, or C-reactive protein levels were detected for either gene. Genetic variation in the CD40 gene is associated with CAC in diabetic families.

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.

Calcium & Bioenergetics

Bioenergetic processes, including cellular respiration and photosynthesis, concern the transformation of energy by cells. Here is the latest research on the role of calcium in bioenergetics.

Atherosclerosis Disease Progression

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.
