The main topics were the hotspots in the field of immunology: New innate sensors in immunity, inflammation and cancer; liver-resident NK cells; T cell exhaustion and immune dynamics; T follicular helper cells; the essential roles of LRRK2 in lung homeostasis and pulmonary fibrosis; drug-loaded tumor microparticles; regulatory B lymphocytes in diseases; new strategies to improve tumor microenvironment.

3. 17 symposia were organized to discuss topics including differentiation and development of immune cells; innate immune recognition, regulation and inflammation response; immunometabolism and immune regulation; COVID-19 immunity and infection immunity; tumor immunity and tumor immunotherapy; autoimmune diseases and allergy diseases; traditional medicine immune regulation; immunological interdisciplinary research. 208 from the received abstracts were selected to give oral presentations in the symposia and 155 were presented as posters. In the “Meet the Editors” symposium senior editors from international journals shared their thoughts on details of scientific publications and answered participants’ questions.

4.
