In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Q: Context: Interleukin-8 (IL-8), a CXC chemokine that induces the migration and proliferation of endothelial cells and smooth muscle cells, is a potent angiogenic factor that may play a role in atherosclerosis. Previously, IL-8 has been reported in atherosclerotic lesions and circulating macrophages from patients with atherosclerosis. Therefore, we sought to determine whether IL-8 plays a role in mediating angiogenic activity in atherosclerosis.', 'Homogenates from 16 patients undergoing directional coronary atherectomy (DCA) and control samples from the internal mammary artery (IMA) of 7 patients undergoing bypass graft surgery were assessed for IL-8 content by specific ELISA, immunohistochemistry, and in situ hybridization for IL-8 mRNA. The contribution of IL-8 to net angiogenic activity was assessed using the rat cornea micropocket assay and cultured cells. IL-8 expression was significantly elevated in DCA samples compared with IMA samples (1.71+/-0.6 versus 0.05+/-0.03 ng/mg of total protein; P<0.01). Positive immunolocalization of IL-8 was found exclusively in DCA tissue sections, and it correlated with the presence of factor VIII-related antigen. In situ reverse transcriptase polymerase chain reaction revealed the expression of IL-8 mRNA in DCA tissue. Corneal neovascular response, defined by ingrowth of capillary sprouts toward the implant, was markedly positive with DCA pellets, but no constitutive vessel ingrowth was seen with IMA specimens. Neutralizing IL-8 attenuated both the in vivo corneal neovascular response and the in vitro proliferation of cultured cells.\Question: Is iL-8 an angiogenic factor in human coronary atherectomy tissue?

A: The results suggest that, in human coronary atherosclerosis, IL-8 is an important mediator of angiogenesis and may contribute to plaque formation via its angiogenic properties.

Q: Context: Although few studies have examined cardiovascular disease in Asian-American subgroups separately, limited data in Asian Americans strongly suggest that some subgroups are at increased risk. The present study examined modifiable cardiovascular risk factor profiles as a function of Asian ethnicity.', 'This descriptive cross-sectional pilot study recruited Asian-American women (N=147) in northeast Florida including Cambodians (n=39), Chinese (n=36), Filipinos (n=49), and Vietnamese (n=23). Risk factors included blood pressure, body mass index, waist circumference and blood lipids.', 'Filipino participants (41%) had 4 risk factors compared to 21% Cambodian, 13% Vietnamese and 0% Chinese. The Chinese had significantly more participants (44%) with the absence of CVD risk factors compared to all other subgroups. Obesity rate (18%), mean BMI: 26 5 kg/m(2) and mean triglycerides (173 103 mg/dL) were highest in Filipinas (n=49). The Chinese (n=36) had a low rate (4%) of obesity with a mean BMI of 23 3 kg/m(2) and the least risk factors along with the lowest triglycerides (88 44 mg/dL). Cambodians (n=39; BMI of 24 3 kg/m(2)) and Vietnamese (n=23; BMI: 22 3 kg/m(2)) had low rates of obesity with comparable rates of unhealthy lipids and hypertension as the Filipinas.\Question: Does one size fit all : cardiovascular health disparities as a function of ethnicity in Asian-American women?

A: Modifiable CVD risk factor profiles significantly differed as a function of ethnicity supporting the premise that Asian-American women cannot be categorized as one group and the traditional "one size fits all" prevention or treatment of CVD risk factors should be re-considered.

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).\Question: Are polyclonal T-cell responses to cytochrome P450IID6 associated with disease activity in autoimmune hepatitis type 2?

A:
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.
