Varol, Aydan Çevik2024-10-292024-10-292024979-889113559-8979-889113467-6https://hdl.handle.net/20.500.11776/12649This chapter examines the roles of light and the circadian rhythm in the response to viral, bacterial, and parasitic infections. Light serves as an environmental cue that synchronizes the circadian rhythm, which regulates immune function. Disruptions in the circadian rhythm, caused by altered light exposure patterns, can significantly impact the immune response of the body. The section explores the influence of light on viral, bacterial, and parasitic infections separately. It discusses how light affects viral replication, the host immune response, and antiviral therapies. It also explores the impact of light on bacterial toxin production, biofilm formation, and antibiotic effectiveness. Additionally, it investigates the influence of light on the life cycles, transmission, and immune evasion mechanisms of parasites. Furthermore, the section highlights the relationship between the circadian rhythm and the immune system. It examines how the circadian clock regulates immune cell function, cytokine production, and susceptibility to infections. It also explores the consequences of disrupted circadian rhythms on immune responses. By exploring these topics, this section contributes to future research and therapeutic interventions targeting a wide range of infections. © 2024 Nova Science Publishers, Inc.
