A novel polymorphism in the extracellular domain 2 (EC2) of FcgammaRIIIA affects ligand binding by natural killer (NK) cells and monocytes from genotyped homozygous normal donors independently of receptor expression. The nonconservative T to G substitution at nucleotide 559 predicts a change of phenylalanine (F) to valine (V) at amino acid position 176. Compared with F/F homozygotes, FcgammaRIIIa expressed on NK cells and monocytes in V/V homozygotes bound more IgG1 and IgG3 despite identical levels of receptor expression. In response to a standard aggregated human IgG stimulus, FcgammaRIIIa engagement on NK cells from V/V (high-binding) homozygotes led to a larger …

Phosphorylation Regulates The Assembly Of Numa In A Mammalian Mitotic Extract, Alejandro Saredi, Louisa Howard, Duane A. Compton

NuMA is a 236 kDa nuclear protein that is required for the organization of the mitotic spindle. To determine how NuMA redistributes in the cell during mitosis, we have examined the behavior of NuMA in a mammalian mitotic extract under conditions conducive to the reassembly of interphase nuclei. NuMA is a soluble protein in mitotic extracts prepared from synchronized cultured cells, but forms insoluble structures when the extract becomes non-mitotic (as judged by the inactivation of cdc2/cyclin B kinase and the disappearance of mpm-2-reactive antigens). These NuMA-containing structures are irregularly shaped particles of 1–2 microm in diameter and their assembly …

To examine Department of Veterans Affairs (VA) and Medicare hospitalizations for elderly veterans with acute myocardial infarction (AMI), their use of cardiac procedures in both systems, and patient mortality. DATA SOURCES: Merging of inpatient discharge abstracts obtained from VA Patient Treatment Files (PTF) and Medicare MedPAR Part A files. A retrospective cohort study of male veterans 65 years or older who were prior users of the VA medical system (veteran-users) and who were initially admitted to a VA or Medicare hospital with a primary diagnosis of AMI at some time from January 1, 1988 through December 31, 1990 (N = …
