🩺 HOW THIS STUDY MIGHT AFFECT RESEARCH,
PRACTICE OR POLICY
Systemic effects of long-term UVR exposure lead to systemic #immunosuppression, which impacts #melanoma & non-melanoma #CancerImmunotherapy

These findings suggest that patients may benefit
from avoiding ☀️sun exposure during #Immunotherapy
Systemic immunosuppression from ultraviolet radiation exposure inhibits cancer immunotherapy
Background Ultraviolet radiation (UVR) affects local cutaneous and systemic immunity acutely. The wavelength, pattern and intensity of UVR exposure, individual skin phototype and immune state of indiv...

In preliminary human data, there is an association between the molecular evidence of repeated ultraviolet radation (UVR) exposure in #dermal #fibroblasts and higher systemic #Tregs

WHAT THIS STUDY ADDS

⇒ Authors show that systemic UVR exposure increases circulating regulatory T cells ( #Tregs ) & induces an #immunosuppressive signature within #colorectal and #melanoma mouse tumors, thereby impairing the efficacy of #immunotherapy

🔬What is already known on this topic

#Ultraviolet radiation (UVR) alters cutaneous (in the skin) and #systemic (across the body) #immunity, but its influence on #immunotherapy outcomes in solid #cancers remains unclear
