CD44 is a multifunctional class I transmembrane glycoprotein that generally acts as a specific receptor for hyaluronic acid, and is responsible for mediating communication and adhesion between adjacent cells and between cells and the extracellular matrix (ECM). It is mainly associated with proteins that monitor the extracellular changes and critical in regulating cell adhesion, proliferation, growth, survival, motility, migration, angiogenesis, and differentiation. Also, CD44 presents cytokines and chemokines to their complimentary receptors on the cellular membrane. CD44 is expressed on the surface of numerous cell types, including leukocytes, fibroblasts, epithelial cells and endothelial cells. Its expression is upregulated on naive T cells after activation via the T cell receptor (TCR) and high expression is maintained indefinitely on memory cells. CD44 interacts with osteopontin and regulates its cellular functions leading to tumour progression. It even interacts with collagen, laminin, and fibronectin where their physiological function is unclear. CD44 is expressed on cancer cell surface and assist haematogenous spread while interacting with P- or L-selectins. It is involved in many types of cancers, including breast, lung, prostate, ovarian, cervical, and colorectal cancers and neuroblastoma. In combination with other surface markers, CD44 can also discriminate between a variety of cancer subsets.
