Objective:
To investigate the B lymphocytes(CD20) and T-lymphocyte subsets (CD4, CD8) expression and clinical significance in chronic rhinosinusitis.
Method:
Immunohistochemical technique was applied to detect the expression of the B lymphocytes (CD20), helper T lymphocytes (CD4) and the cytotoxic T lymphocyte (CD8) in 15 patients with chronic rhinosinusitis without nasal polyps group (CRSsNP). 12 patients of chronic nasal sinusitis with nasal polyp (CRSwNP), 7 cases of recurrent CRSwNP group and 13 patients with inferior turbinate mucosa in the control group. The Mann-Whitney U test was used to analyze CD)20, CD4 and CD8 between the experimental groups and the control group. One- Way ANOVA was used to compare the lymphocyte infiltration between the experiment groups.
Result:
Patients with CRS had higher infiltration of the B lymphocytes (CD20) and T lymphocyte subsets (CD4, CD88) than the patients of the control group (P < 0.05). The expression of T lymphocyte subsets (CD4, CD8) in CRSwNP and recurrent CRSwNP groups was significantly higher than in CRSsNP (P < 0.05). The expression of CD4 in the recurrent CRSwNP group was obviously higher than that in CRSsNP and CRSwNP (P < 0.01).
Conclusion:
The B lymphocytes, helper T cells and cytotoxic T cells have the high expression in CRS groups, which involved with the formation of inflammation. Furthermore nasal polyps are closely related to T lymphocyte infiltration.

Lymphoid Cells and Tissues
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...

Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
