Pathogen recognition research focuses on understanding how the immune system detects and responds to invading pathogens, such as bacteria, viruses, fungi, and parasites. This area of study explores the molecular mechanisms and pathways involved in recognizing and responding to pathogens, including pattern recognition receptors that detect specific microbial molecules, such as lipopolysaccharides or viral RNA. By elucidating these processes, researchers aim to develop new strategies for treating and preventing infectious diseases. This field encompasses a wide range of disciplines, including immunology, microbiology, and molecular biology.
