The authors give clinicomorphological analysis of 100 cases of chronic tonsillitis in young children who had marked regional lymphadenitis in the absence of clinical manifestations of tonsillitis. General and local immunity were examined in these children. Lifetime assessment was made of functional tonsil condition by cytological and microbiological examination of the content of deep lacune parts. Removed palatine tonsils were examined histologically, immunohistochemically and ultrastructurally. Uncommon location of the upper tonsillar pole impairs drainage function of the lacunes, attenuation of lymphoepithelial symbiosis, functional activity of the affected part of the tonsils which give rise to pathological processes in the regional lymph nodes. Impairment of lymph nodes becomes leading in clinical course of the disease.

Background: Cancer immune responses are generated in secondary lymphoid organs, such as the lymph nodes and tonsils. In the current study, transcriptional profiles of peritumoral tonsillar tissues (PTTs) from oropharyngeal cancers (OPCs) were assessed and compared with those of inflammatory tonsils and regional lymph nodes (rLNs).
Methods: RNA samples of PTTs and rLNs from 13 OPCs, and 4 inflammatory tonsils were subjected to microarray analysis, and differentially expressed genes (DEGs) identified from 730 nCounter Panel immune-related genes.
Incidence of adult tonsillectomy for hypertrophic indications in Southwest Finland.

Background: Large palatine tonsils cause a variety of symptoms including obstructive sleep apnea and snoring. In adults, the prevalence of tonsillar hypertrophy remains uncertain.
Aims: We estimated the incidence of tonsillectomy for adult palatine tonsillar hypertrophy using population data and retrospective patient charts.

Collared Peccary (Pecari tajacu, Linnaeus, 1758) is a mammalian Tayassuidae species from tropical to semi-arid areas. The morphological features of the oral cavity in this species were identified and described. Tonsils are secondary lymphoid organs essential for contact with antigens due to food and air intake.

This study investigates a method for programming immune cells using a biomaterial-based system, providing an alternative to traditional cell manipulation techniques. It addresses the limitations of engineered adoptive T cell therapies, such as T cell exhaustion, by introducing a gelatin-hyaluronic acid (GH-GMA) hydrogel system. We characterized tonsil mesenchymal stem cells (TMSCs), lymphatic endothelial cells (T-LECs), stimulated T-CD8 T cells (STCs), and GH-GMA biomaterials.

Background/objectives: Tonsil-derived mesenchymal stem cells (TMSCs) are in the limelight in regenerative medicine due to their high proliferation and differentiation potential. It is important to conduct studies to determine the optimal conditions for achieving the maximum yield while maintaining the optimal differentiation capacity of TMSCs.
Methods: This study explores the impact of serial subculture on TMSCs by analyzing gene expression at passages 2, 4, 6, and 8.
