Characteristics of central nervous system progression in non-small cell lung cancer treated with crizotinib or alectinib.

Cancer Rep (Hoboken) 2021 May 7:e1414. Epub 2021 May 7.

Department of Thoracic Medical Oncology, The Cancer Institute Hospital, Japanese Foundation for Cancer Research, Tokyo, Japan.

Background: Most patients treated with anaplastic lymphoma kinase (ALK)-tyrosine kinase inhibitors for ALK-positive non-small cell lung cancer (NSCLC) develop resistance, leading to metastasis, with progression to the central nervous system (CNS) being a primary concern. Although alectinib has better CNS penetration than crizotinib, patients treated with alectinib also develop CNS progression. CNS metastases more likely occurs during crizotinib treatment due to less blood-brain barrier (BBB) penetration capability than alectinib. Read More

Impact of beta-2 microglobulin expression on the survival of glioma patients via modulating the tumor immune microenvironment.

CNS Neurosci Ther 2021 May 7. Epub 2021 May 7.

Brain Glioma Center & Department of Neurosurgery, Zhongnan Hospital of Wuhan University, Wuhan, Hubei, China.

Aims: High immune cell infiltration in gliomas establishes an immunosuppressive tumor microenvironment, which in turn promotes resistance to immunotherapy. Hence, it is important to identify novel targets associated with high immune cell infiltration in gliomas. Our previous study showed that serum levels of beta-2 microglobulin (B2M) in lower-grade glioma patients were lower than those in glioblastoma patients. Read More

Current and emerging therapies for primary central nervous system lymphoma.

Biomark Res 2021 May 6;9(1):32. Epub 2021 May 6.

Department of Hematology, Huashan Hospital, Fudan University, 12 Wulumuqi Middle Road, Shanghai, 200040, China.

Primary central nervous system (CNS) lymphoma (PCNSL) is a rare type of extranodal lymphoma exclusively involving the CNS at the onset, with diffuse large B-cell lymphoma (DLBCL) as the most common histological subtype. As PCNSL is a malignancy arising in an immune-privileged site, suboptimal delivery of systemic agents into tumor tissues results in poorer outcomes in PCNSL than in non-CNS DLBCLs. Commonly used regimens for PCNSL include high-dose methotrexate-based chemotherapy with rituximab for induction therapy and intensive chemotherapy followed by autologous hematopoietic stem cell transplantation or whole-brain radiotherapy for consolidation therapy.

CNS inflammation after natalizumab therapy for multiple sclerosis: A retrospective histopathological and CSF cohort study.

Brain Pathol 2021 May 6:e12969. Epub 2021 May 6.

Institute of Neuropathology, University Medical Center, Göttingen, Germany.

Natalizumab, a recombinant humanized monoclonal antibody directed against the α4 subunit of the integrins α4ß1 and α4ß7, has been approved for the treatment of active relapsing-remitting MS. Although natalizumab is a highly beneficial drug that effectively reduces the risk of sustained disability progression and the rate of clinical relapses, some patients do not respond to it, and some are at higher risk of developing progressive multifocal leukoencephalopathy (PML). The histopathological effects after natalizumab therapy are still unknown. Read More

CSF lipocalin-2 increases early in subarachnoid hemorrhage are associated with neuroinflammation and unfavorable outcome.

J Cereb Blood Flow Metab 2021 May 5:271678X211012110. Epub 2021 May 5.

Department of Neurology, University of Pittsburgh, Pittsburgh, PA, USA.

Lipocalin-2 mediates neuro-inflammation and iron homeostasis in vascular injuries of the central nervous system (CNS) and is upregulated in extra-CNS systemic inflammation. We postulate that cerebrospinal fluid (CSF) and blood lipocalin-2 levels are associated with markers of inflammation and functional outcome in subarachnoid hemorrhage (SAH). We prospectively enrolled 67 SAH subjects, serially measured CSF and plasma lipocalin-2, matrix metallopeptidase 9 (MMP-9), interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) on post-SAH days 1-5 and assessed outcome by modified Rankin Scale (mRS) every 3 months.

Identification of First-in-Class Inhibitors of Kallikrein-Related Peptidase 6 That Promote Oligodendrocyte Differentiation.

J Med Chem 2021 May 5. Epub 2021 May 5.

Faculty of Sciences and Engineering, IBPS, UMR 8256 CNRS-UPMC, ERL INSERM U1164, Biological Adaptation and Ageing, Sorbonne Université, F-75252 Paris, France.

Multiple sclerosis (MS) is an autoimmune demyelinating disease of the central nervous system (CNS) that causes severe motor, sensory, and cognitive impairments. Kallikrein-related peptidase (KLK)6 is the most abundant serine protease secreted in the CNS, mainly by oligodendrocytes, the myelin-producing cells of the CNS, and KLK6 is assumed to be a robust biomarker of MS, since it is highly increased in the cerebrospinal fluid (CSF) of MS patients. Here, we report the design and biological evaluation of KLK6's low-molecular-weight inhibitors, -aminobenzyl derivatives. Read More

Challenges and Novel Opportunities of Radiation Therapy for Brain Metastases in Non-Small Cell Lung Cancer.

Cancers (Basel) 2021 Apr 29;13(9). Epub 2021 Apr 29.

Department of Radiation Oncology and Protontherapy Unit, Clinica Universidad de Navarra, 28027 Madrid, Spain.

Approximately 20% patients with non-small cell lung cancer (NSCLC) present with CNS spread at the time of diagnosis and 25-50% are found to have brain metastases (BMs) during the course of the disease. The improvement in the diagnostic tools and screening, as well as the use of new systemic therapies have contributed to a more precise diagnosis and prolonged survival of lung cancer patients with more time for BMs development. In the past, most of the systemic therapies failed intracranially because of the inability to effectively cross the blood brain barrier. Read More

J Neuroimmunol 2021 Apr 26;356:577587. Epub 2021 Apr 26.

Department of Neurology, Massachusetts General Hospital, Boston, MA, USA. Electronic address:

Objective: To study long-term outcomes in patients with CNS demyelinating events exposed to TNFa-inhibitors (TNFai), including subsequent clinical relapse, MRI lesions, and use of disease modifying therapy (DMT) for MS.

Brain organoids: a promising model to assess oxidative stress-induced Central Nervous System damage.

Dev Neurobiol 2021 May 3. Epub 2021 May 3.

Department of Biomedical Engineering Sciences, School of Medicine, Loma Linda University, Loma Linda, CA, USA.

Oxidative stress (OS) is one of the most significant propagators of systemic damage with implications for widespread pathologies such as vascular disease, accelerated aging, degenerative disease, inflammation, and traumatic injury. OS can be induced by numerous factors such as environmental conditions, lifestyle choices, disease states, and genetic susceptibility. It is tied to the accumulation of free radicals, mitochondrial dysfunction, and insufficient antioxidant protection, which leads to cell aging and tissue degeneration over time. Read More

Use of a panel of four microRNAs in CSF as a predicted biomarker for postoperative neoangiogenesis in moyamoya disease.

CNS Neurosci Ther 2021 May 4. Epub 2021 May 4.

Department of Neurosurgery, Nanfang Hospital, Southern Medical University, Guangzhou, China.

Introduction And Aims: At present, the treatment for moyamoya disease (MMD) primarily consists of combined direct and indirect bypass surgery. Nevertheless, more than half of indirect bypass surgeries fail to develop good collaterals from the dura and temporal muscle. This study aimed to investigate whether microRNAs (miRNAs) in cerebrospinal fluid (CSF) could serve as biomarkers for the prediction of postoperative collateral formation. Read More
