[Q]: Context: Autoimmune hepatitis type 2 (AIH-2), a severe juvenile liver disorder of unknown etiology and pathogenesis, is characterized by liver-kidney microsomal antibody type 1 targeting cytochrome P450IID6 (CYP2D6) and is associated to HLA DRB1*07. Although CYP2D6 B-cell reactivity has been extensively characterized, little is known about CYP2D6-specific T-cell responses. The aim of the present study was to characterize anti-CYP2D6 cellular immune responses and their possible pathogenic role in patients with AIH-2.', 'We investigated T-cell reactivity against 61 overlapping peptides spanning the full CYP2D6 protein using ex vivo cultures obtained at diagnosis, remission, and relapse. Moreover, CYP2D6-specific T-cell reactivity was investigated in the context of HLA restriction, peptide-binding affinity to HLA DRB1*07, cytokine profile, disease specificity, and clinical course.', 'Proliferative responses to CYP2D6 cluster to 7 antigenic regions in DRB1*07 and to 4 regions in non-DRB1*07 patients. Whereas distinct peptides induce production of interferon gamma, interleukin-4, or interleukin-10, peptides inducing interferon-gamma and proliferation overlap. There is also an overlap between sequences inducing T- and B-cell responses. The breadth (number of epitopes) and intensity (quantity of cytokine produced) of the T-cell response are directly correlated to disease activity (biochemical and histologic markers).
Answer: These data imply that the T-cell response to CYP2D6 in AIH-2 is polyclonal, involves multiple effector types targeting different epitopes, and is associated with hepatocyte damage, knowledge that should form the basis for a more refined therapeutic approach.
[A]: Are polyclonal T-cell responses to cytochrome P450IID6 associated with disease activity in autoimmune hepatitis type 2?


[Q]: Context: Anosognosia is a common manifestation of Alzheimer's disease. There is an association between impaired awareness and frontal-executive cognitive deficits. Anosognosia is also correlated with decreased metabolism in the right hemisphere, particularly in frontal lobe regions.", "To investigate pathological correlates of anosognosia in Alzheimer's disease.", "41 subjects followed longitudinally in the University of Pittsburgh memory disorders clinic and with necropsy verified Alzheimer's disease were divided into two groups, based on previous clinical assessment: +Aware (n = 23) and -Aware (n = 18). A subset analysis matching subjects for dementia severity using mini-mental state examination scores was also carried out (13 +Aware; 13 -Aware). Histopathological data from necropsy brain tissue consisted of senile plaque (SP) and neurofibrillary tangle (NFT) counts (regional density) from four different brain regions in the right and left hemispheres: superior and middle frontal gyri (SMF), superior temporal isocortex (ST), the prosubiculum of the hippocampus (PRO), and the entorhinal cortex (EC).", 'SP density was greater in the right PRO region of -Aware subjects (F = 6.54, p = 0.015) than +Aware subjects. Significant differences between SP or NFT density were not observed in any other regions. In the subset analysis matching for dementia severity, SP density was again greater in the right PRO region of -Aware subjects than in the other regions (F = 12.72, p = 0.002).
Answer: Increased SP density in the right PRO region suggests that selective pathological involvement of this area contributes to awareness deficits in Alzheimer's disease. The putative role of the PRO in self appraisal may reflect its interconnections with other medial temporal and prefrontal regions.

[Q]: Context: Expression of CINCs was regulated differentially in lipopolysaccharide-stimulated rat macrophages. We examined whether the expression of CINCs in lipopolysaccharide-stimulated rat macrophages is similarly inhibited by anti-inflammatory drugs.', 'Rat peritoneal macrophages were stimulated by lipopolysaccharide in the presence of anti-inflammatory steroids (dexamethasone, prednisolone and hydrocortisone) or non-steroidal anti-inflammatory drugs (indomethacin and piroxicam). The production and mRNA expression of three types of CINCs were measured using enzyme-linked immunosorbent assay and northern hybridization.', 'Anti-inflammatory steroids; dexamethasone, prednisolone and hydrocortisone, dose-dependently inhibited the production of CINC-1, -2 and -3, whose inhibitory patterns were similar to each other. Furthermore mRNA expression of each CINC was inhibited by dexamethasone in a dose-dependent manner. In contrast, non-steroidal anti-inflammatory drugs, indomethacin and piroxicam were without effect. Expression of each CINC was regulated differently; the production of CINC-1 reached a maximum at 12 h and then slightly decreased after lipopolysaccharide stimulation, whereas that of CINC-2 and CINC-3 increased up to 24 h. Dexamethasone inhibited the CINCs production and mRNA expression at 9 h after lipopolysaccharide stimulation.
Answer: These results indicate no difference among CINC-1, -2 and -3 in the inhibition of production and mRNA expression of CINCs by anti-inflammatory steroids, although lipopolysaccharide differentially induces expression of each CINC expression in culture of rat macrophages.
[A]:
Is the expression of three types of CINCs by lipopolysaccharide-stimulated rat macrophages inhibited similarly by anti-inflammatory steroids?
