Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Example Input: 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.
Example Output: Is pentraxin 3 reduced in bipolar disorder?

Example Input: Embryonic-like stem cells (ELSCs) express embryonic stem cell-specific marker genes, such as SSEA-4, Oct-4 and Nanog, and can be induced to differentiate into cells of all 3 germ layers. Our preliminary data showed that ELSCs isolated from human bone marrow express multipotent antigen markers and differentiate into multinucleated myotube-like cells more efficiently than do mesenchymal stromal cells (MSCs) isolated from the same source. We investigated the therapeutic effect of ELSCs in dystrophin/utrophin double knock-out (dko) mice, one of the Duchenne muscular dystrophy animal models, by systemically transplanting them through tail-vein injection.', 'ELSCs and MSCs were both isolated from human bone marrow. Two months after equal amounts of ELSCs or MSCs were injected through tail-vein injection, we evaluated skeletal muscle motor function and serum creatine kinase activity and measured dystrophin expression by means of immunostaining, Western blotting and semi-quantitative reverse transcriptase-polymerase chain reaction.', 'ELSCs positive for Oct-4 and Nanog-3 expressed higher levels of SSEA-4, FZD-9 and CD105 and were induced to differentiate into myotube-like cells more efficiently than did MSCs in vitro. Transplantation of ELSCs through the tail vein improved motor function and decreased serum creatine kinase activity at 2 months after cell transplantation. In addition, dystrophin protein and messenger RNA were upregulated and the skeletal muscle histology was improved in these dko mice transplanted with ELSCs.
Example Output: Does systemic delivery of human bone marrow embryonic-like stem cells improve motor function of severely affected dystrophin/utrophin-deficient mice?

Example Input: Regulatory T cell (Treg) is required for the maintenance of tolerance to various tissue antigens and to protect the host from autoimmune disorders. However, Treg may, indirectly, support cancer progression and bacterial infections. Therefore, a balance of Treg function is pivotal for adequate immune responses. Acid sphingomyelinase (ASM) is a rate limiting enzyme involved in the production of ceramide by breaking down sphingomyelin. Previous studies in T-cells have suggested that ASM is involved in CD28 signalling, T lymphocyte granule secretion, degranulation, and vesicle shedding similar to the formation of phosphatidylserine-exposing microparticles from glial cells. However, whether ASM affects the development of Treg has not yet been described.', 'Splenocytes, isolated Naive T lymphocytes and cultured T cells were characterized for various immune T cell markers by flow cytometery. Cell proliferation was measured by Carboxyfluorescein succinimidyl ester (CFSE) dye, cell cycle analysis by Propidium Iodide (PI), mRNA transcripts by q-RT PCR and protein expression by Western Blotting respectively.', 'ASM deficient mice have higher number of Treg compared with littermate control mice. In vitro induction of ASM deficient T cells in the presence of TGF-β and IL-2 lead to a significantly higher number of Foxp3+ induced Treg (iTreg) compared with control T-cells. Further, ASM deficient iTreg has less AKT (serine 473) phosphorylation and Rictor levels compared with control iTreg. Ceramide C6 led to significant reduction of iTreg in both ASM deficient and WT mice. The reduction in iTreg leads to induction of IL-1β, IL-6 and IL-17 but not IFN-γ mRNA levels.
Example Output:
Is acid Sphingomyelinase ( ASM ) a Negative Regulator of Regulatory T Cell ( Treg ) Development?
