Objective:
To assess the role of CCR10 in innate lymphoid cells (ILCs) response in radiation-induced skin damage.
Material And Methods:
CCR10+/- and CCR10-/- mice were treated with either a single dose of 5 Gy or 5 Gy everyday for 6 days with a total dose of 30 Gy with X-ray. ILCs from the skin were isolated and analyzed by flow cytometry 3 and 10 days after irradiation. A mouse model of radio-dermatitis was used to assess the skin damage 10 days after 6 × 5 Gy irradiation.
Results:
Skin ILCs were decreased in both CCR10+/- and CCR10-/- mice 3 days after single irradiation (p < .05). However, the skin inflammation disappeared and ILCs returned to normal levels 10 days after single irradiation. ILCs of both genotypes were also decreased after 6 × 5 Gy irradiation, but the percentage of skin ILCs in CCR10-/- mice was lower than that in CCR10+/- mice 10 days after irradiation. The immunohistochemistry results showed that CCR10-/- mice had more severe skin inflammation than CCR10+/- mice.
Conclusion:
CCR10-/- mice had lower percentages of ILCs and more skin damage than CCR10+/- mice after irradiation. These findings indicate that skin ILCs are regulated by CCR10, which might be a potential target for reducing the radio-dermatitis.
