Context: Immunologic abnormalities have been found in bipolar disorder but pentraxin 3, a marker of innate immunity, has not been studied in this population.', 'Levels of pentraxin 3 were measured in individuals with bipolar disorder, schizophrenia, and non-psychiatric controls. Linear regression models were used to compare the pentraxin 3 levels in each of the psychiatric groups to that in the control group, adjusting for demographic and clinical variables. Logistic regression models were used to calculate the odds ratios associated with levels of pentraxin 3 which differed from specified levels of the control group.', 'The sample consisted of 831 individuals: 256 with bipolar disorder, 309 with schizophrenia, and 266 without a psychiatric disorder. The levels of pentraxin 3 in the bipolar disorder, but not in the schizophrenia, group were significantly lower than those of controls, adjusting for age, gender, race, maternal education, smoking status, and body mass index (t = -3.78, p < 0.001). The individuals with bipolar disorder also had significantly increased odds of having low levels of pentraxin 3 relative to both the 10th and 25th percentile level of the controls and significantly decreased odds of having a level greater than the 75th and the 90th percentile level of the controls, adjusting for the same covariates.
Answer: Individuals with bipolar disorder have low levels of pentraxin 3 which may reflect impaired innate immunity. An increased understanding of the role of innate immunity in the etiopathogenesis of bipolar disorder might lead to new modalities for the diagnosis and treatment of this disorder.
Is pentraxin 3 reduced in bipolar disorder?

Context: Allopregnanolone (ALLO) is a physiologically relevant neurosteroid modulator of GABA(A) receptors, and it exhibits a psychopharmacological profile that closely resembles the post-ingestive effects of ethanol. The 5alpha-reductase inhibitor finasteride (FIN), which inhibits biosynthesis of ALLO and structurally related neurosteroids, was previously demonstrated to reduce the maintenance of limited-access ethanol consumption. The primary aim of the current work was to determine whether FIN would reduce the acquisition of drinking in ethanol-naïve mice.', 'Male C57BL/6J (B6) mice were acclimated to a reverse light/dark schedule, and were provided ad libitum access to chow and water. Following habituation to vehicle injections (VEH; 20% w/v beta-cyclodextrin; i.p.) administered 22-hour prior to drinking sessions with water only, mice were divided into 3 treatment groups: vehicle control (VEH), 50 mg/kg FIN (FIN-50), and 100 mg/kg FIN (FIN-100). Twenty-two hours after the first treatment, mice were permitted the inaugural 2-hour limited access to a 10% v/v ethanol solution (10E) and water. The acquisition of 10E consumption and underlying drinking patterns were assessed during FIN treatment (7 days) and subsequent FIN withdrawal (13 days) phases.', 'FIN dose-dependently blocked the acquisition of 10E drinking and prevented the development of ethanol preference, thereby suggesting that the GABAergic neurosteroids may be important in the establishment of stable drinking patterns. FIN-elicited reductions in 10E intake were primarily attributable to selective and marked reductions in bout frequency, as no changes were observed in bout size, duration, or lick rates following FIN treatment. FIN-treated mice continued to exhibit attenuated ethanol consumption after 2 weeks post-treatment, despite a full recovery in brain ALLO levels. A second study confirmed the rightward and downward shift in the acquisition of ethanol intake following 7 daily FIN injections. While there were no significant group differences in brain ALLO levels following the seventh day of ethanol drinking, ALLO levels were decreased by 28% in the FIN-50 group.
Answer: Although the exact mechanism is unclear, FIN and other pharmacological interventions that modulate the GABAergic system may prove useful in curbing ethanol intake acquisition in at-risk individuals.
Does inhibition of 5alpha-reduced steroid biosynthesis impede acquisition of ethanol drinking in male C57BL/6J mice?

Context: FAAH degrades endocannabinoids and fatty acid amides. FAAH inhibition reduces micturition frequency and counteracts bladder overactivity in rats. We studied the effects of the peripherally active selective FAAH inhibitor URB937, and the CB1 and CB2 receptor antagonists rimonabant and SR144528, respectively, on single unit afferent activity of primary bladder afferents in rats.', 'Female Sprague Dawley® rats were anesthetized. Single unit afferent activity of Aδ or C-fibers from the L6 dorsal roots was recorded during bladder filling before and after URB937 administration with or without rimonabant or SR144528. Drugs (1 mg/kg) were given intravenously. FAAH, CB1 and CB2 expression, and expression of the sensory marker CGRP in\xa0the L6 dorsal root ganglion were compared by immunofluorescence.', 'A total of 102 single afferent fibers (48 Aδ and 54 C-fibers) were isolated from 57 rats. URB937 decreased single unit afferent activity of C-fibers to a mean ± SEM of 78% ± 9% and of Aδ-fibers to a mean of 67% ± 7% while increasing bladder compliance to a mean of 116% ± 3%. The effects of URB937 on single unit afferent activity and bladder compliance were counteracted by rimonabant or SR144528. Rimonabant increased single unit afferent activity of\xa0each fiber type but SR144528 affected only Aδ-fiber activity. CGRP positive L6\xa0dorsal root ganglion neurons showed strong FAAH, CB1 and CB2 staining.
Answer: To our knowledge we report for the first time that inhibiting peripheral FAAH depresses the Aδ and C-fiber activity of primary bladder afferents via CB1 and CB2 receptors. CB antagonists alone exerted facilitatory effects on single unit afferent activity during bladder filling in rats. The endocannabinoid system may be involved in physiological control of micturition as regulators of afferent signals.

Does inhibition of peripheral FAAH depress activities of bladder mechanosensitive nerve fibers of the rat?
