Diagnostic utility of APOE, soluble CD40, CD40L, and Abeta1-40 levels in plasma in Alzheimer’s disease

By Ait-ghezala G, Abdullah L, Volmar CH, Paris D, Luis CA, Quadros A, Mouzon B, Mullan MA, Keegan AP, Parrish J, Crawford FC, Mathura VS, Mullan MJ. Cytokine. 2008 Nov;44(2):283-7. A continuous inflammatory state is associated with Alzheimer’s disease (AD) evidenced by an increase in proinflammatory cytokines around beta-amyloid (Abeta) deposits. In addition, functional loss […]

CD40/CD40L interaction induces Abeta production and increases gamma-secretase activity independently of tumor necrosis factor receptor associated factor (TRAF) signaling.

By Volmar CH, Ait-Ghezala G, Frieling J, Weeks OI, Mullan MJ. Exp Cell Res. 2009 Aug 1;315(13):2265-74. CD40, a member of tumor necrosis factor receptor superfamily, and its cognate ligand CD40L are both elevated in the brain of Alzheimer’s disease (AD) patients compared to controls. We have shown that pharmacological or genetic interruption of CD40/CD40L […]

CD40L induces Abeta production via signaling by the granulocyte macrophage colony stimulating factor (GM-CSF)

Alzheimer’s disease (AD) is the most common type of dementia in the elderly. AD is mainly characterized by the accumulation of a small molecule (known as amyloid beta (Abeta)) in the brain. Many researchers have shown that the molecule CD40L is elevated in AD patients. Roskamp Institute research group headed by Dr. Michael Mullan also […]
