However, the existence of the negatively charged region may not be the only reason contributing the invasion. Overall structure of OspC may play an equally important role. Recent studies showed that, in serum of patients demonstrating erythema migrans (early stage of Lyme disease), IgM antibody has been found to interact with OspC <ref>Wilske B, Preac-Mursic V, Schierz G, Busch K.
