Part 1. Definition
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.
Part 2. Example
Context: Chronic rhinosinusitis (CRS) is a heterogeneous disease with an uncertain pathogenesis. Group 2 innate lymphoid cells (ILC2s) represent a recently discovered cell population which has been implicated in driving Th2 inflammation in CRS; however, their relationship with clinical disease characteristics has yet to be investigated. The aim of this study was to identify ILC2s in sinus mucosa in patients with CRS and controls and compare ILC2s across characteristics of disease. A cross-sectional study of patients with CRS undergoing endoscopic sinus surgery was conducted. Sinus mucosal biopsies were obtained during surgery and control tissue from patients undergoing pituitary tumour resection through transphenoidal approach. ILC2s were identified as CD45(+) Lin(-) CD127(+) CD4(-) CD8(-) CRTH2(CD294)(+) CD161(+) cells in single cell suspensions through flow cytometry. ILC2 frequencies, measured as a percentage of CD45(+) cells, were compared across CRS phenotype, endotype, inflammatory CRS subtype and other disease characteristics including blood eosinophils, serum IgE, asthma status and nasal symptom score. 35 patients (40% female, age 48 ± 17 years) including 13 with eosinophilic CRS (eCRS), 13 with non-eCRS and 9 controls were recruited. ILC2 frequencies were associated with the presence of nasal polyps (P = 0.002) as well as high tissue eosinophilia (P = 0.004) and eosinophil-dominant CRS (P = 0.001) (Mann-Whitney U). They were also associated with increased blood eosinophilia (P = 0.005). There were no significant associations found between ILC2s and serum total IgE and allergic disease. In the CRS with nasal polyps (CRSwNP) population, ILC2s were increased in patients with co-existing asthma (P = 0.03). ILC2s were also correlated with worsening nasal symptom score in CRS (P = 0.04).
Question: Are group 2 innate lymphoid cells ( ILC2s ) increased in chronic rhinosinusitis with nasal polyps or eosinophilia?
Answer: As ILC2s are elevated in patients with CRSwNP, they may drive nasal polyp formation in CRS. ILC2s are also linked with high tissue and blood eosinophilia and have a potential role in the activation and survival of eosinophils during the Th2 immune response. The association of innate lymphoid cells in CRS provides insights into its pathogenesis.
Explanation: The output says that ILC2s are elevated in patients with CRSwNP and that they may drive nasal polyp formtion in CRS. The output also says that ILC2s are linked with blood eosinophilia and hence, it completely answers the question on the basis of the information in the context.
Part 3. Exercise
Context: Visceral mechanoreceptors are critical for perceived sensations and autonomic reflex control of gastrointestinal function. However, the molecular mechanisms underlying visceral mechanosensation remain poorly defined. Degenerin/epithelial Na+ channel (DEG/ENaC) family ion channels are candidate mechanosensory molecules, and we hypothesized that they influence visceral mechanosensation. We examined the influence of the DEG/ENaC channel ASIC1 on gastrointestinal mechanosensory function, on gastric emptying, and on fecal output. We also compared its role in gastrointestinal and somatic sensory function.', 'To assess the role of ASIC1 we studied wild-type and ASIC1-/- mice. Reverse-transcription polymerase chain reaction (RT-PCR) and Western blot analysis determined expression of ASIC1 messenger RNA and protein in vagal and spinal sensory ganglia. Colonic, gastroesophageal, and cutaneous afferent fibers were characterized by functional subtype and their mechanical stimulus-response relationships were determined. Gastric emptying was determined by using a 13CO2 breath test. Behavioral tests assessed somatic mechanical and thermal sensitivity.', 'ASIC1 was expressed in sensory ganglia and was lost after disruption of the ASIC1 gene. Loss of ASIC1 increased mechanosensitivity in all colonic and gastroesophageal mechanoreceptor subtypes. In addition, ASIC1-/- mice showed almost double the gastric emptying time of wild-type mice. In contrast, loss of ASIC1 did not affect function in any of the 5 types of cutaneous mechanoreceptors, nor did it affect paw withdrawal responses or fecal output.\Question: Does the ion channel ASIC1 contribute to visceral but not cutaneous mechanoreceptor function?

ASIC1 influences visceral but not cutaneous mechanoreceptor function, suggesting that different mechanisms underlie mechanosensory function in gut and skin. The role of ASIC1 is highlighted by prolonging gastric emptying of a meal in ASIC1-/- animals.
