WebOct 30, 2024 · A possible explanation of this phenomenon is PD-L1 upregulation caused by smoking [24,25]. It has been shown that elevated levels of PD-L1 expression increased the efficiency of anti-PD-1/PD-L1 treatment [26,27]. As a result, increased activities of ICIs may trigger thyroid abnormalities because of the high T cell activity.
