Introduction

The immune system is a multifunctional defense system that has evolved over a long time in animals, and has the function of protecting animals against pathogenic infections, preventing tumor formation and maintaining homeostasis. Immunology is a biological discipline that studies the composition and function of the immune system in animals and reveals its mechanism of action. With the application of cell biology and molecular biology techniques to immunological research, the mechanism of action of the immune system has been explored and discovered in depth, thus ushering in the era of molecular immunology. The special techniques and methods in immunological research have also greatly promoted the advance in life sciences, molecular medicine and other related research fields, and molecular immunology has become an important core content in the field of biomedical research.
