    مستخلص: After his initial disease progression while receiving anti-PD-L1 therapy, repeat biopsy demonstrated no tumor PD-L1 staining (with limited stromal PD-L1 positivity), and PD-L2 remained strongly positive (70%; Fig 1C). This finding suggests that the significance of PD-L2 positivity in response to PD-L1 or PD-1 targeted therapies may be a useful subject of study. Although anecdotal, this case report demonstrates an important clinical finding: patients who become resistant to anti-PD-L1 may still benefit from PD-1 targeted therapies, possibly due to a switch from dependency on PD-L1 to PD-L2 for maintenance of immunosuppression. However, the presence of consistently high PD-L2 staining argues against a direct mechanism of PD-L2-mediated de novo resistance to anti-PD-L1 therapy. [Extracted from the article]
