Blocking exposed PD-L1 elicited by nanosecond pulsed electric field reverses dysfunction of CD8+ T cells in liver cancer.

abstract：:Receptors for all classes of steroid hormones were identified in cytosols of adenocarcinoma of the lung. In contrast, the incidence of receptor in squamous cell carcinoma was limited and small cell carcinomas appeared devoid of receptor. Receptor binding was of high affinity, saturable and localized to the 8, 6-7 and ...
