The Eagle Bioscience’s Noradrenaline Sensitive ELISA was highlighted in a recent publication on how brain injuries instruct bone marrow cellular lineage destination to reduce neuroinflammation. Check out the abstract and full article below.
Abstract
Acute brain injury mobilizes circulating leukocytes to transmigrate into the perivascular space and brain parenchyma. This process amplifies neural injury. Bone marrow hematopoiesis replenishes the exhausted peripheral leukocyte pools. However, it is not known whether brain injury influences the development of bone marrow lineages and how altered hematopoietic cell lineages affect neurological outcome. Here, we showed that bone marrow hematopoietic stem cells (HSCs) can be swiftly skewed toward the myeloid lineage in patients with intracerebral hemorrhage (ICH) and experimental ICH models. Lineage tracing revealed a predominantly augmented hematopoiesis of Ly6Clow monocytes infiltrating the ICH brain, where they generated alternatively activated macrophages and suppressed neuroinflammation and brain injury. The ICH brain uses β3-adrenergic innervation that involves cell division cycle 42 to promote bone marrow hematopoiesis of Ly6Clow monocytes, which could be further potentiated by the U.S. Food and Drug Administration-approved β3-adrenergic agonist mirabegron. Our results suggest that brain injury modulates HSC lineage development to curb distal brain inflammation, implicating the bone marrow as a unique niche for self-protective neuroimmune interaction that might be exploited to obtain therapeutic effects.
