Kallikrein-related peptidase 7 overexpression in melanoma cells modulates cell adhesion leading to a malignant phenotype.

abstract：:Aberrant microglial activation and neuroinflammation is a pathological hallmark of amyotrophic lateral sclerosis (ALS). Fractalkine (CX3CL1) is mostly expressed on neuronal cells. The fractalkine receptor (CX3CR1) is predominantly expressed on microglia. Many progressive neuroinflammatory disorders show disruption of ...
