Накратко на български

Биологичните механизми, чрез които имунните клетки сътрудничат за активиране на паметта на Т-клетките след инфекция или ваксинация, са в центъра на анализа. По-доброто разбиране на тези процеси помага при разработването на ваксини и осигуряването на дълготрайна защита срещу патогени.

Targeting dendritic cell plasticity to modulate antigen-specific T cell recall responses in human

The human immune system has the ability to fight various infectious diseases. A hallmark of the immune system is the generation of an immunological memory. Memory cells can be detected in humans for several decades following an infection or a vaccination. While the generation of memory T cells have been well described, a significant gap of knowledge remains on how immune cells cooperate to reactivate the immunological memory. A better understanding of these biological mechanisms can have an important impact on the design of vaccines and the generation of long-term protection against pathogens. In this interdisciplinary program, we used an experimental systematic approach, together with forefront technologies and integrative analyses, to investigate the biological mechanisms by which key human immune cells cooperate to effectively reactivate memory T cells. We identified unprecedented key cellular and molecular mechanisms associated with the functional reactivation and proliferation of memory T cells. From this work, several original scientific publications are currently under preparations.

Цел на проекта

The human immune system has the ability to fight various infectious diseases or self-cells turning malignant. Dendritic cells (DCs) are innate immune sensors and professional antigen presenting cells that initiate the development of adaptive immune responses towards the formation of memory cells. Very important studies deciphered the various signals in DCs to effectively polarize naïve T cells. However, a significant gap of knowledge remains on how DCs can mediate and influence antigen-specific T cell recall responses.In this program, we aim to investigate how the different human DC subsets can modulate antigen-specific T cell recall responses directed against influenza (Flu) epitopes. To this end, we have designed a set of highly integrated work packages:WP1: Using a systematic experimental approach of challenging co-cultures of pure DCs (6 different subsets) and Flu-specific T cells from healthy subjects, we will generate a functional atlas revealing the impact of the different DC subsets on antigen-specific T cell recall responses. T cell response status will be assessed at the protein level using phenotypic and functional approaches on multimer positive T cells.WP2: Using CITE-seq technology together with cutting-edge system biology platforms, we will interrogate the transcriptomic programs and molecular pathways associated with antigen-specific T cell recall responses following stimulation with the various DC subsets.WP3: As a complementary analysis of the data generated in WP2, we will perform TCR repertoire analysis to compare the clonal composition of the responding antigen-specific T cells.This program represents an ambitious and promising project that will generate novel biological insights into fundamental immunological mechanisms of human DC-T cell communication. Such information could have direct clinical impact on the design of therapeutic DC-based vaccines, immunotherapies targeting DCs or T cell expansion protocols for adoptive transfer therapy
