Summary of "Plaque-associated myeloid cells derive from resident microglia in an Alzheimer's disease model."

Alzheimer's disease (AD) is accompanied by a robust inflammatory response mediated by plaque-associated myeloid cells of the brain. These cells exhibit altered gene expression profiles and serve as a barrier, preventing neuritic dystrophy. The origin of these cells has been controversial and is of therapeutic importance. Here, we genetically labeled different myeloid populations and unequivocally demonstrated that plaque-associated myeloid cells in the AD brain are derived exclusively from resident microglia, with no contribution from circulating peripheral monocytes.

Medical and Biotech [MESH] Definitions

PROGESTERONE-producing cells in the CORPUS LUTEUM. The large luteal cells derive from the GRANULOSA CELLS. The small luteal cells derive from the THECA CELLS.

Stem cells derived from HEMATOPOIETIC STEM CELLS. Derived from these myeloid progenitor cells are the MEGAKARYOCYTES; ERYTHROID CELLS; MYELOID CELLS; and some DENDRITIC CELLS.

Clonal expansion of myeloid blasts in bone marrow, blood, and other tissue. Myeloid leukemias develop from changes in cells that normally produce NEUTROPHILS; BASOPHILS; EOSINOPHILS; and MONOCYTES.

An extramedullary tumor of immature MYELOID CELLS or MYELOBLASTS. Granulocytic sarcoma usually occurs with or follows the onset of ACUTE MYELOID LEUKEMIA.

Method for measuring viral infectivity and multiplication in cultured cells. Clear lysed areas or plaques develop as the viral particles are released from the infected cells during incubation. With some viruses, the cells are killed by a cytopathic effect; with others, the infected cells are not killed but can be detected by their hemadsorptive ability. Sometimes the plaque cells contain viral antigens which can be measured by immunofluorescence.
