Packet J: Tossup 7

Gomori-positive subsets of these non-muscle cells are rich in degenerated mitochondria. Corkscrew-shaped aggregates called Rosenthal fibers are mostly composed of these cells’ namesake fibrillary (10[1])acidic protein. EAAT1/2 (“E-A-A-T-one-two”) facilitates the reuptake of glutamate into these cells. (10[2])In response to injury, chondroitin (-5[3])sulfate (-5[1])proteoglycans produced by these cells accumulate in their namesake scars. The alkylating (10[1])agent (-5[1])temozolomide (-5[1])is used to treat WHO Grade III and IV blastomas (10[1])of these cells. The Bergmann (-5[1])type of these cells is abundant in (-5[1])the Purkinje (10[1])layer. (-5[2])Synaptic (-5[2])pruning is (10[1]-5[2])mediated (-5[5])by (-5[1])phagocytic (10[2]-5[3])“micro” (-5[1])forms (10[1]-5[1])of these cells. (10[4]-5[3])Star-shaped (10[2])types (10[1])of these cells (10[4]-5[1])have foot (10[2])processes (10[1])that (-5[1])form (10[1])the blood-brain barrier. (10[3]-5[2])For 10 points, (10[1])name these (-5[1])supportive non-neuronal (10[2]-5[1])cells (10[2]-5[2])of the CNS. (10[1])■END■ (10[23]0[24])

ANSWER: glial cells [accept neuroglial cells or neuroglia; accept macroglia or microglia; accept astroglia or astrocytes; accept radial glial cells or RGCs or radial glial progenitor cells or RGPs; accept Muller glia; accept Bergmann glia; accept glial fibrillary acidic protein or GFAP; accept glial scars or gliosis; accept glioblastomas or astrocytomas; prompt on brain cells; prompt on macrophages or leukocytes or phagocytes until read by asking “what non-immune function do they also serve?”; reject “neurons” or “nerve cells”]
