CD63 and hereditary sensory and autonomic neuropathy: Higher expression of CD63 was observed for all FQs and concentrations tested, although differences were only significant at 0.2 mg/mL for CIP and MOX when data were analyzed in terms of percentage (P = 0.04 for MOX; P = 0.01 for CIP) (Fig. 1A) and SI (P = 0.03 for MOX; P = 0.04 for CIP) (Fig. 1C).
