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: Environmental conditions (eg, latitude) play a critical role in the susceptibility and severity of many autoimmune disorders, including multiple sclerosis (MS). Here, we investigated the mechanisms underlying the beneficial effects of immune regulatory processes induced in the skin by moderate ultraviolet B (UVB) radiation on central nervous system (CNS) autoimmunity.', 'Effects of UVB light were analyzed in a murine model of CNS autoimmunity (experimental autoimmune encephalomyelitis). Additionally, patients with relapsing-remitting MS were treated with narrowband UVB phototherapy. Immunomodulatory effects were examined in skin biopsies, serum samples, and immune cells of the peripheral blood.', 'Regulatory T cells (Tregs), which are induced locally in the skin-draining lymph nodes in response to UVB exposure, connect the cutaneous immune response to CNS immunity by migration to the sites of inflammation (blood, spleen, CNS). Here, they attenuate the inflammatory response and ameliorate disease symptoms. Treg-inducing tolerogenic dendritic cells (DCs) were further necessary for induction of this systemic immune regulation by UVB radiation, because ablation of Langerhans cells abolished the UVB-induced phenotype. MS patients treated with UVB phototherapy showed an increase in induced Tregs and tolerogenic DCs accompanied by the downregulation of the T-cell effector cytokine interleukin 21. The treatment further induced elevated serum levels of vitamin D.\Question: Does ultraviolet B light attenuate the systemic immune response in central nervous system autoimmunity?
[A]: Local UVB radiation of the skin influences systemic immune reactions and attenuates systemic autoimmunity via the induction of skin-derived tolerogenic DCs and Tregs. Our data could have implications for the understanding or therapeutic modulation of environmental factors that influence immune tolerance.

[Q]: Context: In Crohn's disease (CD), rapid response to anti-tumor necrosis factor therapy improves short- and medium-term outcomes, but the relationship between early remission (ER) and long-term remission is unclear.", 'This exploratory analysis of PRECiSE 3 (NCT00160524) assessed whether ER after initiation of certolizumab pegol predicted long-term remission.', 'Patients enrolled in PRECiSE 3 had completed PRECiSE 1 or 2, two randomized placebo-controlled studies for moderate to severe CD, and received open-label certolizumab pegol 400mg every 4 weeks for a total treatment duration of 7.5 years. Time to loss of remission between patients with and without ER (Harvey-Bradshaw Index 4 at or before Week 6 of PRECiSE 1 or 2) was compared by log-rank test of Kaplan-Meier estimates.', 'At baseline, patients with (n=242) and without (n=148) ER had mean (standard deviation [SD]) durations of CD of 6.8 (6.6) and 7.4 (7.8) years, mean (SD) CD Activity Index scores of 280.3 (53.4) and 311.1 (55.5), with 45.5% and 41.9% of patients having ileocolonic CD, and median C-reactive protein concentrations of 8.0 and 5.0mg/L, respectively. Median certolizumab pegol plasma concentrations during the first 6 weeks of therapy were similar in both groups. Mean time to loss of remission was significantly longer in patients with versus without ER (2.77 vs. 1.14 years, p<0.0001).\Question: Does early remission status predict long-term outcomes in patients with Crohn 's disease treated with certolizumab pegol?
[A]: In certolizumab pegol-treated patients with CD, ER appears to be an important predictor of long-term clinical remission. Prospective trials are needed to determine whether ER improves other long-term outcomes.

[Q]: Context: Partial adherence to antihypertensive therapy remains a public health challenge and may be associated with increased cardiovascular risk. We quantitatively evaluated cardiovascular risk inherent in partial therapy adherence in spontaneously hypertensive rats with accelerated hypertension.', 'Adult spontaneously hypertensive rats were divided into 5 groups; Group 1 (controls) did not receive any treatment, whereas all other rats (Groups 2-5) were given nitric oxide synthase inhibitor N-nitro-l-arginine methyl ester (L-NAME) to exacerbate hypertension. Group 2 (untreated/nonadherers) was given L-NAME but not antihypertensive medication; Group 3 (Perfect Adherers) was treated daily with candesartan (10 mg/kg); Group 4 was given candesartan 3 times a week, whereas Group 5 received candesartan only during the last 6 days of the 3-week experiment (Partial Adherers). At the end, indices of systemic and regional (kidneys, brain, and heart) hemodynamics, and indices of left ventricular function were determined.', 'Treatment with L-NAME aggravated hypertension, adversely affected target organ blood flows and resistances, and grossly impaired ventricular function. Perfect adherence with candesartan completely reversed the adverse cardiovascular effects of L-NAME intervention. In partial adherers (Groups 4 and 5), arterial pressure decreased and reached control values. However, target organ hemodynamics and heart function showed only slight improvements, if any.\Question: Does partial adherence to antihypertensive therapy fail to achieve full cardiovascular benefits in hypertensive rats?
[A]:
The results demonstrate that partial adherence to therapy reduces arterial pressure, but may not prevent target organ damage. If replicated in humans, these results may have important clinical implications in hypertensive patients.
