The microenvironment of brain metastases from solid tumors.

TLDR
In this paper, the authors discuss unique aspects of the TME in the context of brain metastases and pathways through which they may hold the key to the discovery of new and effective therapies for patients with brain metastasis.
Abstract
Brain metastasis (BrM) is an area of unmet medical need that poses unique therapeutic challenges and heralds a dismal prognosis. The intracranial tumor microenvironment (TME) presents several challenges, including the therapy-resistant blood-brain barrier, a unique immune milieu, distinct intercellular interactions, and specific metabolic conditions, that are responsible for treatment failures and poor clinical outcomes. There is a complex interplay between malignant cells that metastasize to the central nervous system (CNS) and the native TME. Cancer cells take advantage of vascular, neuronal, immune, and anatomical vulnerabilities to proliferate with mechanisms specific to the CNS. In this review, we discuss unique aspects of the TME in the context of brain metastases and pathways through which the TME may hold the key to the discovery of new and effective therapies for patients with BrM.

CCL2 recruits inflammatory monocytes to facilitate breast-tumour metastasis

TL;DR: The mechanistic link between CCL2 expression and macrophage infiltration are correlated with poor prognosis and metastatic disease in human breast cancer and the origin of these macrophages is defined by showing that Gr1-positive inflammatory monocytes are preferentially recruited to pulmonary metastases but not to primary mammary tumours in mice.

A Perivascular Niche for Brain Tumor Stem Cells

TL;DR: This work shows that endothelial cells interact closely with self-renewing brain tumor cells and secrete factors that maintain these cells in a stem cell-like state, and proposes that brain CSCs are maintained within vascular niches that are important targets for therapeutic approaches.
