Bacterial endotoxin induces [Ca2+]i transients and changes the organization of actin in microglia.

abstract：:Neuroinflammation perpetuates neuronal damage in many neurological disorders. Activation of resident microglia and infiltration of monocytes/macrophages contributes to neuronal injury and synaptic damage. Noninvasive imaging of these cells in vivo provides a means to monitor progression of disease as well as assess ef...
