Genome-wide methylation changes in maternal microchimeric cells from Mmc+ and Mmclow offspring mice

ABSTRACT: During mammalian pregnancy, immune cells are vertically transferred from mother to fetus. The functional role of these maternal microchimeric cells (MMc) is largely unknown. We show that MMc induce a preferential differentiation of hematopoietic stem and progenitor cells towards myelopoiesis in bone marrow of fetal mice, and improves resilience against cytomegalovirus infection in neonates. In humans, low MMc counts in cord blood are associated with an increased number of infections in the first year of life primarily in male newborns. Taken together, MMc boost neonatal immunity in mice and humans to mitigate the risk for early life infections.

Gene expression profiling of LMC and MMC motor neurons in SMA mice

Project description:Spinal muscular atrophy (SMA) is a neurodegenerative disease which exhibits selective motor neuron death caused by a ubiquitous deficiency of the survival motor neuron (SMN) protein. It remains unclear how the ubiquitous reduction of SMN lead to death in selective motor neuron pools. Medial motor neuron columns (MMC) are vulnerable, whereas lateral motor columns (LMC) are resistant to motor neuron death in SMA. Here we performed microarray and pathway analysis comparing cholera toxin subunit B (CTb) labeled vulnerable MMC and resistant LMC of pre-symptomatic SMA with corresponding motor neuron columns of control mice to identify pathways involved in selective motor neuron death in SMA. WT is FVB. SMN is Delta7 (SMNΔ7;SMN2;Smn-) on a FVB background.
