Intrinsic membrane properties are important in the regulation of motoneuronal output during such behaviours as locomotion. A conductance through L-type calcium channels has been implicated as an essential component in the transduction of motoneuronal input to output during locomotion. Given the developmental changes in calcium currents occurring postnatally(More)
The ability of the central nervous system (CNS) to generate innate immune responses was investigated in an in vitro model of CNS infection. Cultures containing CNS cells were infected with mouse hepatitis virus-JHM, which causes fatal encephalitis in mice. Immunostaining indicated that viral infection had a limited effect on culture characteristics, overall(More)
Diabetes mellitus accelerates the development of atherosclerotic cardiovascular diseases. Monocyte adhesion is an early cellular event of atherogenesis. Elevated levels of glyLDL were common in diabetic patients. Our previous studies indicated that HSF1 and p22-phox (a subunit of the NOX complex) were involved in glyLDL-induced up-regulation of PAI-1 in(More)
BACKGROUND Hepatitis C virus (HCV) infection is associated with clinical depression,a condition that is aggravated on interferon-based therapy. In HCV infection, men often appear more resilient to depression than women. However, men are subject to depression in diseases that tend to be comorbid in HCV-infected. AIM This study examined whether HCV-infected(More)
Genetic diversity related to the human immune response is a key factor in individual and population survival throughout human history. Population diversity in disease susceptibility and resistance have been identified and linked to differences in cytokine mRNA and protein expression levels. Polymorphisms in the regulatory regions of cytokine genes can(More)
There is much interest in the utility of exogenous IL-12 as a biologic adjuvant in immediate hypersensitivity and infectious or parasitic diseases where the induction of Th1 responses is strongly associated with protective immunity. Using an immediate hypersensitivity model in which C57Bl/6 mice immunized with OVA (alum) normally generate Th2-dominated(More)
UNLABELLED The host immune response is a critical determinant in viral infection outcome. Epidemiological studies indicate that North American indigenous peoples are more resistant to chronic HCV infection than other populations. Due to the prominence of IL-10 in chronic HCV infection, we investigated the genetic tendency to produce IL-10 in Caucasian (CA)(More)
Endogenous IL-12 production is hypothesized to play an essential role preventing spontaneous expression of type 2 responses, acting as a natural inhibitor limiting development of immediate hypersensitivity. Here, IL-12-deficient p35(- / -) and p40(- / -) mice were used to examine the role of endogenous IL-12 and p40 homodimer during in vivo development of(More)
Genetic differences in immune regulators influence disease resistance and susceptibility patterns. There are major health discrepancies in immune-mediated diseases between Caucasians and Canadian Aboriginal people, as well as with other indigenous people of the Americas. Environmental factors offer a limited explanation as Aboriginal people also demonstrate(More)
Differences in disease outcome between the highly neurovirulent MHV-JHM and mildly neurovirulent MHV-A59 have been attributed to variations within the spike (S) glycoprotein. Previously, we found that MHV-JHM neurovirulence was marked by diminished expression of interferon-gamma (IFN-gamma) mRNA and a reduced presence of CD8 T cells in the CNS concomitant(More)
