IFN-alpha exercises multiple immune modulatory and antiviral activities and has been suggested to play a critical role in the pathogenesis of systemic lupus erythematosus (SLE). Plasmacytoid dendritic cells (pDCs) release IFN-alpha upon TLR7 and TLR9 ligation. With respect to the nine times higher incidence of SLE in women and the clinical use of synthetic(More)
Fifty-two cases of motor neuron disease seen in two Halifax hospitals were reviewed.Thirty-three (63.5%) had amyotrophic lateral sclerosis, 14 (26.9%) had primary muscular atrophy, four (7.7%) had bulbar palsy and one (1.9%) had primary lateral sclerosis. There were no unusual features in this series when compared with a similar series from the United(More)
Plasmacytoid dendritic cells (pDCs) are unique with respect to their capacity to produce unsurpassed amounts of IFN-alpha and coexpress TLR7 and TLR9, mediating IFN-alpha production. Although TLRs are critical receptors of innate immunity, little is known about the immunological effects of TLR7/TLR9 costimulation. We have analyzed the effects of TLR7/TLR9(More)
Aggressive periodontitis (AgP) is a severe periodontal disease characterized by rapid destruction of the tissues supporting the teeth in otherwise healthy individuals. The frequency of the interleukin-4 homozygous -34TT and -590TT genotype was increased in patients in comparison with controls. This study aimed to test the functional effect of this specific(More)
Two cluster analytic studies were conducted to explore groupings of patients in a heterogeneous psychiatric population. Study 1 (N = 170) provided support for the derivation by a cluster analytic method of five meaningful clinical groups of patients. Based on an extensively modified inventory and a different population of psychiatric patients, results from(More)
Aggressive periodontitis (AgP) is a specific form of periodontal disease, with rapid destruction of the tissues supporting the teeth in otherwise young healthy individuals. We recently showed a higher frequency of the interleukin-4 (IL-4) -34TT and -590TT genotype in AgP patients compared to controls (P<0.05). Herein, we demonstrated that this specific IL-4(More)
