"Following differentiation with LPS or a combination of LPS and IFN-gamma microglia exhibited high KV 1.3 current densities ( approximately 50 pA/pF at 40 mV) and virtually no KCa 3.1 and Kir currents while microglia differentiated with IL-4 exhibited large Kir 2.1 currents ( approximately 10 pA/pF at -120 mV). KCa 3.1 currents were generally low"xsd:string
