Pediatric photosensitivity [PDF]

Photodermatology, Photoimmunology & Photomedicine, 2012
SummaryPhotosensitivity is a rarely encountered problem in the pediatric population. It may be caused by a diverse group of primary, idiopathic photosensitivity conditions, or may reflect photoexacerbation of an existing dermatosis. In addition, there are several genodermatoses, metabolic disorders, and connective tissue disorders that can present with

Genome‐Wide CRISPR Screen Identifies a microRNA Orchestrating Pleiotropic Resistance to Targeted Therapy and T Cell Immunity in Melanoma

Advanced Science, EarlyView.
A genome‐wide microRNA CRISPR screen identifies miR‐18a as a master regulator of cross‐resistance in melanoma. Loss of miR‐18a activates the AJUBA–YAP/Hippo axis to confer BRAFi resistance and enhances THBS1–CD47 interaction to impair CD8+ T cell immunity. hnRNP A1 is identified as an upstream regulator of miR‐18a processing.

Light‐Activatable Nitric Oxide Release via Intramolecular Electron Transfer for Tumor Pyroptosis Induction

Advanced Science, EarlyView.
This work proposes a novel strategy to fabricate unimolecular pyroptosis photoinitiators activated by deep‐red light at low light doses. It relies on a photosensitization mechanism to trigger nitric oxide (NO) release from benzisothiadiazole‐based N‐nitrosanilines without modification of nitro moieties, thereby boosting pyroptosis‐mediated ...

TME/NIR Dual‐Responsive Zinc‐Based Targeted Nanoagonist for Multimodal Amplification of STING‐Mediated Cancer Immunotherapy

Advanced Science, EarlyView.
A multifunctional nanoagonist (cDZ@IP) enables nano‐metabolite–driven multimodal activation of the STING pathway and enhanced immune recognition, achieving potent antitumor immunity and suppressing tumor growth and metastasis. This strategy highlights the rational design of therapeutic metabolites and establishes a new paradigm bridging nanomedicine ...
