Abstract

Oligodendroglia (ODG) are unique among glial cell types in their capacity to activate complement in the absence of antibody, causing insertion of the potentially damaging membrane attack complex (MAC) into the plasma membrane. Using microfluorimetry of indo-1 fluorescence we have detected a complex oscillatory [Ca2+]i response in ODG following exposure to sublethal dilutions of serum-derived complement. Oscillations were transitory and preceded complete and stable return to resting [Ca2+]i levels, whereas nonoscillating ODG underwent rapid lysis. Depletion of the terminal complement component C9 from serum removed the oscillatory stimulus, which could be restored by reconstitution with purified C9. Exposure to the C9-homologous peptide melittin produced [Ca2+]i oscillations similar in pattern to those induced by whole serum. However, this type of response could not be reproduced by Ca2+ ionophores or mechanical wounding, suggesting that oscillations cannot be provoked by Ca2+ influx alone and depend on the presence of the MAC or a pore-forming lesion. Oscillations were not prevented in the continuous presence of caffeine, demonstrating independence from caffeine-releasable intracellular stores. Inhibition of the endoplasmic reticular Ca(2+)-ATPase with thapsigargin produced an abrupt elevation in [Ca2+]i but did not alter the latency between exposure to serum and the initial complement-induced transient. However, the slope of this initial transient was considerably reduced and oscillations suppressed, demonstrating dependence of the oscillatory mechanism on functional endoplasmic reticular Ca2+ stores. The coincidence of ODG recovery with oscillating [Ca2+]i suggests that the complex calcium signal that follows MAC attack may stimulate repair or protective mechanisms.
