DQA (n= 8) amd DQB (n= 6) mRNA expression was quantified using relative optical densities (ROD) on Northern autoradiograms

	White matter			Gray matter
	Narcoleptic		Control	Narcoleptic		Control
		p			p
DQA/β-actin	0.52 ±  0.06	0.002	0.25 ±  0.04	0.86 ±  0.19	0.036	0.39 ±  0.07
DQA/β-tubulin	3.07 ±  0.73	0.016	0.97 ±  0.23	1.51 ±  0.53	ns	0.75 ±  0.16
DQB/β-actin	0.20 ±  0.02	ns	0.15 ±  0.03	0.50 ±  0.05	ns	0.63 ±  0.11
DQB/β-tubulin	1.66 ±  0.27	0.023	0.81 ±  0.16	0.79 ±  0.07	ns	1.29 ±  0.22

ROD values (means ± SEM) were calculated using β-actin and β-tubulin measurements as internal controls. Comparisons are based on post hoc t test comparisons between the narcoleptic and the control group. ns, Not significant.
