Cellometer T4 studies immune response to Delftia bacteria sometimes found in IV catheters

North Carolina State University investigated the immune response to the gram-negative bacteria Delftia spp., a water and soil species which has been identified in IV catheters. Delftia strain Cs1-4 and THP-1 cells (monocytes) were employed. Cellometer Auto T4 provided cell viability measurements with Trypan Blue to ensure a constant concentration of viable monocytes were present throughout experimentation. After Delftia stimulation of the monocytes, monocyte mortality rose, as did the production of TNF and pro-inflammatory proteins. This research confirms that Delftia does induce a pro-inflammatory reaction in monocytes and suggests that more research into the downstream effects of this bacteremia-associated strain [...]

Cellometer T4 work in Adoptive Cell Transfer examines gender differences in pathology after stroke

Oregon Health & Science University researchers continued their studies into the gender-related differences in peripheral immune system response after stroke that produce greater downstream damage in males than females, and what role the spleen may play in those differences. The goal of this work was to uncover which subset of immune system cells may contribute to those pathogenic effects after a stroke and how they vary by gender. Using primary leukocytes from transgenic mice and adoptive T-cell transfer, scientists injected specific cell types into splenectomized male and female mice 24 hours after stroke was induced. The Cellometer Auto T4 maintained [...]
