Estrogen activation of microglia underlies the sexually dimorphic differences in Nf1 optic glioma-induced retinal pathology [PDF]

, 2016
Children with neurofibromatosis type 1 (NF1) develop low-grade brain tumors throughout the optic pathway. Nearly 50% of children with optic pathway gliomas (OPGs) experience visual impairment, and few regain their vision after chemotherapy.

Optic nerve sheath meningioma exhibits neural niche‐associated transcriptomic features and rare copy number variation‐linked evolution

Brain Pathology, EarlyView.
Optic nerve sheath meningiomas are typically NF2‐intact with few copy number alterations and are generally clinically indolent. Rare aggressive recurrences are associated with progressive accumulation of copy number variations, including CDKN2A/B homozygous deletion, 1q gain, and 14q loss.

Losartan Enhances Radiosensitivity by Reversing Immunosuppressive Tumor Microenvironment Induced by Radiotherapy in TNBC

Cancer Science, EarlyView.
Our study demonstrates that the angiotensin receptor blocker losartan enhances the efficacy of radiotherapy in triple‐negative breast cancer by reversing the immunosuppressive tumor microenvironment. Losartan reprograms tumor‐associated macrophages, inhibits myeloid‐derived suppressor cell function, and boosts CD8+ T‐cell activity.
