Whole Body Irradiation Induces Cutaneous Dendritic Cells Depletion via NF-κB Activation

Cellular Physiology and Biochemistry, 2013
Background: Effect of ionizing radiation on cutaneous dendritic cells (cDC) is critical to its influence on immune status of the skin, which plays an important role in the progression and recovery of radiation skin sickness.

Sterol synthesis after whole body roentgen irradiation [PDF]

Acta Radiologica, 1957
Male rats were irradiated with 400 r whole body irradiation. The in vivo incorporation of 2-C/sup 14/-acetate in liver cholesterol decreases during the first day after irradiation and subsequently increases. The hepatic cholesterol concentration falls immediately, rises above normal and slowly falls again.

Effect of Low-Dose Gamma Radiation and Lipoic Acid on High- Radiation-Dose Induced Rat Brain Injuries

Dose-Response, 2021
Aim This work aims to investigate the possible radio-adaptive mechanisms induced by low-dose (LD) whole-body γ-irradiation alone or combined with alpha-lipoic acid (ALA) administration in modulating high-dose (HD) head irradiation–induced brain injury in
