Cerebrospinal fluid microRNA profile in leptomeningeal metastasis patients [LM vs non-LM]
Phenotypic states of leptomeningeal metastasis
This study aimed to identify specific CSF miRNAs for diagnosing and monitoring leptomeningeal metastasis with lung adenocarcinoma. In discovery phase, we performed miRNA microarray analysis in CSF samples from leptomeningeal metastasis patients and non-leptomeningeal metastasis controls.

Single-cell atlas of human leptomeningeal metastasis
Leptomeningeal metastasis (LM), or spread of cancer cells into the cerebrospinal fluid, is characterized by a rapid onset of debilitating neurological symptoms and markedly bleak prognosis. The lack of reproducible in vitro and in vivo models has prevented development of novel, LM-specific therapies...

We investigated the functional effect of dura-derived leptomeningeal matastasis (LM)-associated macrophages (dLAMs) on the cerebrospinal fluid (CSF) niche during LM outgrowth. Using lung cancer leptomeningeal metastasis models of Cx3cr1CreER:mTmG mice with tamoxifen administration, we achieved dLAMs...

Single-cell atlas of dura cells from non-tumor or leptomeningeal metastasis mice
The early diagnosis of leptomeningeal disease is a challenge because it is an asymptomatic pathology in the early stages. Hence, it is highly relevant to identify a panel of biomarkers to help in the diagnosis and/or prognostic. For this purpose, we have explored a multipronged proteomics approaches...

We performed scRNA-seq on the cells isolated from the dura mater in non-tumor control mice and leptomeningeal metastasis (LM) mice with LLC-LeptoM cell inoculation for 7 or 12 days.
