Transplantation-related mortality (TRM) is high after HLA-mismatched umbilical cord blood (UCB) transplantation (UCBT). In utero, exposure to noninherited maternal antigen (NIMA) is recognized by the fetus, which induces T regulator cells to that haplotype. It is plausible that UCBTs in which recipients are matched to donor NIMAs may alleviate some of the excess mortality associated with this t...
In clinical practice, cardiovascular (CV) risk stratification is based on the assessment of individual risk factors. Still many cardiovascular deaths occur in individuals who were not at high risk according to the current CV risk stratification models as the Systematic COronary Risk Evaluation chart (SCORE) and Framingham Risk Score. By measuring morphological and÷or functional abnormalities in...
Phosphorylation of histone H3 serine 10 correlates with chromosome condensation and is required for normal chromosome segregation in Tetrahymena. This phosphorylation is dependent upon activation of the NIMA kinase in Aspergillus nidulans. NIMA expression also induces Ser-10 phosphorylation inappropriately in S phase-arrested cells and in the absence of NIMX(cdc2) activity. At mitosis, NIMA bec...
Temperature sensitive (ts) nimA mutants of Aspergillus nidulans arrest at a unique point in G2 which is post activation of CDC2. Here we show that this G2 arrest is due to loss of nimA function and that it is dependent on BIMAAPC3, a component of the anaphase promoting complex/cyclosome (APC/C). Whereas nimA single mutants arrested in G2 with decondensed chromatin and interphase microtubule arr...
Non-inherited maternal antigens (NIMA) are those protein products derived from polymorphic genes that the mothers express but not the offspring. During normal human pregnancy, a bidirectional regulation occurs in such a way that the maternal immune system tolerates the inherited paternal antigens (IPA) expressed by the fetus and the developing fetal immune system tolerates NIMA. The process by ...
Compulsory exposure to genetically foreign maternal tissue imprints in offspring sustained tolerance to noninherited maternal antigens (NIMA). Immunological tolerance to NIMA was first described by Dr. Ray D. Owen for women genetically negative for erythrocyte rhesus (Rh) antigen with reduced sensitization from developmental Rh exposure by their mothers. Extending this analysis to HLA haplotype...
BACKGROUND Many organisms undergo closed mitosis and locate tubulin and mitotic kinases to nuclei only during mitosis. How this is regulated is unknown. Interestingly, the NIMA kinase of Aspergillus nidulans interacts with two nuclear pore complex (NPC) proteins and NIMA is required for mitotic localization of the Cdk1 kinase to nuclei. Therefore, we wished to define the mechanism by which the ...
The NIMA kinase is required for mitotic nuclear pore complex disassembly and potentially controls other mitotic-specific events. To investigate this possibility, we imaged NIMA-green fluorescent protein (GFP) using four-dimensional spinning disk confocal microscopy. At mitosis NIMA-GFP locates to spindle pole bodies (SPBs), which contain Cdk1/cyclin B, followed by Aurora, TINA, and the BimC kin...
Exposure to maternal tissue during in utero development imprints tolerance to immunologically foreign non-inherited maternal antigens (NIMA) that persists into adulthood. The biological advantage of this tolerance, conserved across mammalian species, remains unclear. Here, we show maternal cells that establish microchimerism in female offspring during development promote systemic accumulation o...
Entry into mitosis requires p34(cdc2), which activates downstream mitotic events through phosphorylation of key target proteins. In Aspergillus nidulans, the NIMA protein kinase has been identified as a potential downstream target and plays a role in regulating chromatin condensation at mitosis. nimA- mutants arrest in a state that physically resembles interphase even though p34(cdc2) is fully ...
