| Abstract | To investigate the effect of chronic stress on inflammation of nasal mucosa using an unpredictable chronic mild stress (UCMS) model to mimic chronic stress-like disorders. We divided BALB/c mice into four groups: control (n = 5), UCMS-exposed (n = 5), AR-induced (n = 5) and UCMS-exposed/AR-induced groups (n = 5). We measured cortisol as a marker of chronic stress and cytokines such as IFN-γ and IL-4, IL-5 representing Th1 and Th2 response, respectively, and we also examined the nasal mucous membrane histologically. UCMS exposure was confirmed by an increase in the levels of cortisol. Although there was no significant difference in Th1 cytokine (IFN-γ) levels within the groups, Th2 cytokine (IL-5) levels were significantly increased in stressed groups (UCMS-exposed and UCMS-exposed/AR-induced groups) compared to non-stressed groups (control and AR-induced groups). The histological examination of the nasal mucous membrane after antigen challenge in stressed group revealed severe dilation of blood vessels and injured olfactory hairs on the olfactory mucous membrane and severe swelling in the respiratory epithelium, compared to non-stressed group. These results suggest that chronic stress can aggravate inflammation of nasal mucosa in AR-induced mice model by shifting to the Th2 response by up-regulation of Th2 cytokines expression. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
