Ionizing Radiation and the Immune Response, Volume 376, Part A reviews the latest updates on the immune response induced by ionizing radiations. Sections discuss NK functions in radio-induced immune response, TRT and immune response, Radio-induced immune response and lipid metabolism, Effect of protons and heavy ions on immune response, Effect of flashtherapy and mini beam on immune response, Radio-induced lymphopenia, CT to potentiate radio-induced immune response, Impact of RT on healthy tissues (inflammation), Radio-induced macrophagic response, To use nanoparticles and ionizing radiations to modulate immune response: opinion of the chemist, biologist and clinician, and more. Additional sections touch on the Effect of low dose radiation on radio-induced immune response, Role of Dendritic cells in radiation-induced immune response, Relationship between the tumor microenvironment and the efficacy of the radiotherapy/immunotherapy combination+A23, and Biomarkers of radiation induced response to optimize radio-immunotherapy combination.
