Phagocytosis prevents the release of potentially harmful or immunogenic materials from dying cells. Milk fat globule epidermal growth factor (EGF)-factor VIII (MFG-E8) mediates the clearance of apoptotic cells. We have previously shown that the administration of MFG-E8-rich exosomes from immature dendritic cells promotes the phagocytosis of apoptotic cells and improves survival in sepsis. Becau...
Myocardial infarction (MI) results in the generation of dead cells in the infarcted area. These cells are swiftly removed by phagocytes to minimize inflammation and limit expansion of the damaged area. However, the types of cells and molecules responsible for the engulfment of dead cells in the infarcted area remain largely unknown. In this study, we demonstrated that cardiac myofibroblasts, wh...
We review earlier proposals for E8 family unification, and discuss why recent work of Kovner and Shifman on condensates in supersymmetric YangMills theories suggests the reconsideration of E8 supersymmetric Yang-Mills as a family unification theory.
Milk fat globule-epidermal growth factor 8 (MFG-E8), a glycoprotein secreted from various cells, enhances engulfment of apoptotic cells by forming a link between phosphatidylserine on apoptotic cells and α(v)β(3)-integrin on phagocytes. This process is essential for maintaining the host immune system under physiological conditions. Apart from this scavenging function, MFG-E8 also directly regul...
Developmental stage-, subset-, and lineage-specific CD8 enhancers have been identified recently by transgenic reporter analyses. Enhancer E8(II) (CIV-4,5) is active in both immature double-positive thymocytes (DP) and mature CD8 single-positive (SP) thymocytes and T cells, whereas E8(I) (CIII-1,2) directs expression only in mature cells. In mice lacking either E8(I) (CIII-1,2) or E8(II) (CIV-4,...
This is a revised version of the rst part of 8]. Each two-graph is in one-to-one correspondence with a set of equiangular lines. This implies that a two-graph is represented by a system of vectors of equal odd norm with mutual inner products
Nanomolar β-amyloid peptide (Aβ) can induce neuronal loss in culture by activating microglia to phagocytose neurons. We report here that this neuronal loss is mediated by the bridging protein lactadherin/milk-fat globule epidermal growth factor-like factor 8 (MFG-E8), which is released by Aβ-activated microglia, binds to co-cultured neurons and opsonizes neurons for phagocytosis by microglia. A...
Phagocytes, including macrophages, recognize phosphatidylserine exposed on apoptotic cells as an "eat me" signal. Milk Fat Globule EGF Factor VIII (MFG-E8) is secreted by one subset of macrophages, whereas Tim4, a type I membrane protein, is expressed by another. These proteins bind tightly to phosphatidylserine on apoptotic cells and enhance their engulfment by macrophages. To study the contri...
Satellite cells function as precursor cells in mature skeletal muscle homeostasis and regeneration. In healthy tissue, these cells are maintained in a state of quiescence by a microenvironment formed by myofibers and basement membrane in which LAMININs (LMs) form a major component. In the present study, we evaluated the satellite cell microenvironment in vivo and found that these cells are enca...
