Бета-амилоид является важным фактором риска и играет центральную роль в возникновении и прогрессировании болезни Альцгеймера. Однако вопрос о влиянии бета-амилоида на гиппокампальный нейрогенез во взрослом мозге остается открытым.</p><p>Цель исследования – изучение влияния процесса обучения на нейрогенез, пролиферацию, выживаемость и миграцию клеток в норме и при экспериментальной болезни Альцгеймера.</p><sec><title>Материал и методы</title><p>Материал и методы. Исследование выполнено на самцах зрелых крыс линии Wistar в возрасте 7 мес. Опытная группа – животные с экспериментальной болезнью Альцгеймера после введения бета-амилоида 1-42 в CA1 зону гиппокампа билатерально по 5 мкл. Контрольная группа – ложно-оперированные животные, которым вводили растворитель для бета-амилоида – фосфатно-солевого буфера – в CA1 зону билатерально по 5 мкл. Для оценки рабочей памяти, а также консолидации памяти использовали нейроповеденческое тестирование в водном лабиринте Морриса. Изучение миграции клеток осуществляли путем введения бромдезоксиуридина (50 мг/кг). Экспрессию молекул-маркеров нейрогенеза (Ki-67, PSA-NCAM, PCNA) в гиппокампе исследовали методом иммуногистохимии с последующей конфокальной микроскопией.</p></sec><sec><title>Результаты</title><p>Результаты. Показано, что моделирование болезни Альцгеймера приводит к нарушениям когнитивных функций и запоминания у животных. В группе с экспериментальной болезнью Альцгеймера выявлено снижение уровня пролиферации клеток (р = 0,043), нарушение миграции (р = 0,031), но не выживаемости клеток (р = 0,985) по сравнению с контрольной группой. Обучение в водном лабиринте Морриса животных с экспериментальной болезнью Альцгеймера способствует миграции клеток-предшественников по ростральному миграционному пути (р = 0,011). Количество нейробластов (р = 0,809) и пролиферация клеток-предшественников нейронов (р = 0,083) значимо не меняется по сравнению с группой без обучения.</p></sec><sec><title>Заключение</title><p>Заключение. При моделировании болезни Альцгеймера у животных наблюдается когнитивная дисфункция, снижение уровня пролиферации и миграции клеток, что свидетельствует о нарушении нейрогенеза за счет токсического действия амилоида. Обсуждается связь полученных результатов с механизмами развития локальной инсулинорезистентности.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aims</title><p>Aims. Alzheimer’s disease is a multifactorial neurodegenerative disease characterized by the presence of amyloid beta peptide containing plaques, and neurofibrillary tangles. Beta-amyloid is a major risk factor and it plays a central role in the onset and progression of Alzheimer’s disease. However, question of the influence of beta-amyloid on neurogenesis in the hippocampus in the adult brain is still open. The purpose of this paper is to study cognitive functions and their association with proliferation, survival and migration of newly-formed cells in normal adult rat brain and in the experimental Alzheimer’s disease.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Rats (Wistar, males, 7 months) were used. Experimental group (Alzheimer’s disease model with the intrahippocampal administration of beta-amyloid 1-42 (5 µl) bilaterally in the CA1 area) and a control group (sham-operated animals with the intrahippocampal administration of Phosphate buffered salin (5 µl) bilaterally in the CA1) have been tested. The study was conducted from February to July. Neurobehavioral test (Morris water maze) was used to assess working memory and memory consolidation. The study of cell migration was performed by introducing bromodeoxyuridine (50 mg/kg). Expression of neurogenesis markers in the subgranular zone of the dentate gyrus of the hippocampus was studied has been studied with indirect immunohistochemistry for free-floating sections followed by the confocal microscopy.</p></sec><sec><title>Results</title><p>Results. Modelling of Alzheimer’s disease leads to impaired cognitive function and memory in animals. We found that these events were associated with the suppression of proliferative (р = 0,043) and migratory activity of brain cells (р = 0,031), but not survival of cells (p = 0,985) compared to the control group.Training in Morris water maze of animals with experimental Alzheimer’s disease promotes migration of progenitor cells along the rostral migration way (р = 0,011) compared with the group without training. However, the number of neuroblasts (р = 0,809) and proliferation of neuronal progenitor cells (p = 0,083) were not significantly affected compared with the group without training.</p></sec><sec><title>Conclusions</title><p>Conclusions. Decreased level of brain cells proliferation, alterations in their migration and development of cognitive dysfunction have been found in the rat model of Alzheimer’s disease, thus suggesting impairment of neurogenesis induced by amyloid. Possible involvement of local insulin resistance into the development of neurogenesis alterations is discussed.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>PCNA</kwd><kwd>Ki-67</kwd><kwd>BrdU</kwd><kwd>миграция клеток</kwd><kwd>болезнь Альцгеймера</kwd><kwd>инсулинорезистентность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>PCNA</kwd><kwd>Ki-67</kwd><kwd>BrdU</kwd><kwd>cell migration</kwd><kwd>Alzheimer’s disease</kwd><kwd>insulin resistance</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">В.В.Волкова (педиатрический факультет КГМУ им. проф.
