Прогрессирование пародонтита зависит не только от бактерий, поскольку неадекватный иммунный ответ на микроорганизмы может ускорить развитие пародонтита. Однако точные механизмы развития иммунных реакций остаются неясными. Недавние исследования подчеркивают существование типичного врожденного ответа резидентных и экстравазированных иммунных клеток.</p><sec><title>Цель работы</title><p>Цель работы. Исследовать количественный состав нерезидентных субпопуляций лимфоцитов в слюнной жидкости и изучить механизмы взаимодействия клеточного звена врожденной и адаптивной иммунной системы при хроническом генерализованном пародонтите различной степени тяжести.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Обследовано 49 человек в возрасте 26–67 лет обоего пола с диагнозом «хронический пародонтит» (K05.3 по МКБ-10). Группа сравнения – из 17 человек в возрасте 26–44 лет с отсутствием заболеваний пародонта. Состояние клеточного звена адаптивной и местной иммунной системы ротовой полости оценивалось по следующим фенотипам: CD3–CD16+56+; CD3+CD16+56+; CD3+; CD3+HLA-DR+; CD19+, CD19+HLA-DR+; CD19+CD5+CD27–; CD19+CD5–СD 27–; CD19+СD5–CD27+.</p></sec><sec><title>Результат</title><p>Результат. Количество T-NK-клеток снижалось при легкой степени пародонтита и увеличивалось при тяжелой степени. Аналогично CD3+HLA-DR+ снижались при легкой степени пародонтита [Me = 0,148 кл/мкл] и увеличивались при средней [Me = 0,247 кл/мкл] и тяжелой степени [Me = 0,448 кл/мкл]. Количество В-лимфоцитов с фенотипом CD19+, CD19+CD5+, CD19+CD5–CD27+ снижалось до единичных клеток в микролитре при развитии заболевания.</p></sec><sec><title>Вывод</title><p>Вывод. Дисбаланс иммунной системы, вызванный патогенной колонизацией пародонта, при разных степенях тяжести является важным фактором возникновения и развития пародонтита, при котором определенную роль играют различные подмножества В-клеток адаптивной иммунной системы, тесно взаимодействующие с клеточным звеном врожденной мукозальной иммунной системы.</p></sec></abstract><trans-abstract xml:lang="en"><p>Periodontal bacterial bioflm causes an innate and adaptive immune response of the host mucosa, leading to inﬂammation and destruction of the tissues supporting the periodontal. The progression of periodontitis depends not only on bacteria, since an inadequate immune response to microorganisms can accelerate the development of periodontitis. However, the exact mechanisms of the development of immune reactions remain unclear. Recent studies emphasize the existence of a typical innate response of resident and extravasated immune cells.</p><sec><title>Objective</title><p>Objective. To investigate the quantitative composition of non-resident subpopulations of lymphocytes in salivary ﬂuid and to study the mechanisms of interaction of the cellular link of the innate and adaptive immune system in chronic generalized periodontitis of varying severity.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 49 people aged 26–67 years of both sexes were examined with a diagnosis of chronic periodontitis. The comparison group consisted of 17 people aged 26–44 years with no periodontal diseases. The state of the cellular link of the adaptive and local immune system of the oral cavity was assessed by the following phenotypes: CD3–CD16+56+; CD3+CD16+56+; CD3+; CD3+HLA-DR+; CD19+, CD19+HLA-DR+; CD19+CD5+CD27–; CD19+CD5–СD 27–; CD19+СD5–CD27+.</p></sec><sec><title>Results</title><p>Results. The number of T-NK cells decreased with a mild degree of periodontitis and increased with a severe degree. Similarly, CD3+HLA-DR+ decreased with mild periodontitis [Me = 0.148 cells/µl] and increased with moderate [Me = 0.247 cells/µl] and severe [Me = 0.448 cells/µl]. The number of B-lymphocytes with the CD19+, CD19+CD5+, CD19+CD5–CD27+ phenotype decreased to single cells per microliter during the development of the disease.</p></sec><sec><title>Conclusion</title><p>Conclusion. The imbalance of the immune system caused by pathogenic colonization of the periodontium, at different degrees of severity, is an important factor in the occurrence and development of periodontitis, in which various subsets of B cells of the adaptive immune system play a certain role, closely interacting with the cellular link of the innate mucosal immune system</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>пародонтит</kwd><kwd>В-лимфоциты</kwd><kwd>T-NK-клетки</kwd><kwd>врожденный мукозальный иммунитет</kwd></kwd-group><kwd-group xml:lang="en"><kwd>periodontitis</kwd><kwd>B-lymphocytes</kwd><kwd>T-NK cells</kwd><kwd>innate mucosal immunity</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Арзуманян В.Г., Белохвостикова Т.С., Вавилова Т.В. и др.
