Journal ArticleDOI
Human Decidual Natural Killer Cells Are a Unique NK Cell Subset with Immunomodulatory Potential
Louise A. Koopman,Hernan D. Kopcow,Basya Rybalov,Jonathan E. Boyson,Jordan S. Orange,Frederick Schatz,Rachel Masch,Charles J. Lockwood,Asher D. Schachter,Peter J. Park,Jack L. Strominger +10 more
TL;DR: Natural killer cells constitute 50–90% of lymphocytes in human uterine decidua in early pregnancy and are compared with the CD56bright and CD56dim peripheral NK cell subsets by microarray analysis, with verification of results by flow cytometry and RT-PCR.
Journal ArticleDOI
A gene expression signature associated with “K-Ras addiction” reveals regulators of EMT and tumor cell survival
Anurag K. Singh,Patricia Greninger,Daniel R. Rhodes,Louise A. Koopman,Sheila Violette,Nabeel Bardeesy,Jeff Settleman +6 more
TL;DR: Findings indicate that epithelial differentiation and tumor cell viability are associated, and that EMT regulators in "K-Ras-addicted" cancers represent candidate therapeutic targets.
Journal ArticleDOI
TGFβ promotes conversion of CD16+ peripheral blood NK cells into CD16-NK cells with similarities to decidual NK cells
Derin B. Keskin,David S.J. Allan,Basya Rybalov,Milena M. Andzelm,Joel N. H. Stern,Hernan D. Kopcow,Louise A. Koopman,Jack L. Strominger +7 more
TL;DR: During pregnancy the uterine decidua is populated by large numbers of natural killer cells with a phenotype CD56superbrightCD16−CD9+KIR+ distinct from both subsets of peripheral blood NK cells, and these progenitors produced NK cells when cultured in conditioned medium from decidual stromal cells supplemented with IL-15 and stem cell factor.
Journal ArticleDOI
Wiskott–Aldrich syndrome protein is required for NK cell cytotoxicity and colocalizes with actin to NK cell-activating immunologic synapses
Jordan S. Orange,Narayanaswamy Ramesh,Eileen Remold-O'Donnell,Yoji Sasahara,Louise A. Koopman,Michael Byrne,Francisco A. Bonilla,Fred S. Rosen,Raif S. Geha,Jack L. Strominger +9 more
TL;DR: It is reported that WAS patients have increased percentages of peripheral blood NK cells and that fresh enriched NK cells from two patients with a WASp mutation have defective cytolytic function.
Journal ArticleDOI
Viral evasion of natural killer cells
TL;DR: These NK cell–specific evasion mechanisms fall into distinct mechanistic categories used in numerous virus families, including means of escaping detection by both the innate and adaptive immune responses.
