Measles virus continues to be a major killer of children, claiming roughly one million lives a year. Measles virus infection causes profound immunosuppression, which makes measles patients susceptible to secondary infections accounting for high morbidity and mortality. The Edmonston strain of measles virus, and vaccine strains derived from it, use as a(More)
The contractile effects of alpha-adrenoceptor agonists and field electrical stimulation were investigated pharmacologically in canine isolated tracheobronchial lymph nodes. Addition of noradrenaline (NA), phenylephrine (Phe) and UK14,304 caused dose-related contractions of the isolated lymph nodes. Pretreatment with prazosin (3 x 10(-9), 3 x 10(-8) and 3 x(More)
Pathogens or pathogen-associated molecular patterns can signal to cells of the innate immune system and trigger effective adaptive immunity. However, relatively little is known about how the innate immune system detects tissue injury or necrosis. Evidence suggests that the release of heat-shock proteins (HSPs) may provide adjuvant-like signals, but the(More)
Interferon (IFN)-alpha and -beta are the main cytokines for innate immune responses against viral infections. To replicate efficiently in the hosts, viruses have evolved various countermeasures to the IFN response. The V protein of measles virus (MV) has been shown to block IFN-alpha/beta signalling. Here, the wild-type IC-B strain of MV was shown to grow(More)
Wild-type strains of measles virus (MV) isolated in B95a cells use the signalling lymphocyte activation molecule (SLAM; also known as CD150) as a cellular receptor, whereas the Edmonston strain and its derivative vaccine strains can use both SLAM and the ubiquitously expressed CD46 as receptors. Among the major target cells for MV, lymphocytes and dendritic(More)
Signalling lymphocyte activation molecule (SLAM, also known as CD150), a membrane glycoprotein involved in lymphocyte activation, has two extracellular immunoglobulin superfamily domains, V and C2. It has been shown previously that human SLAM is a cellular receptor for measles virus (MV) and that its V domain is necessary and sufficient for receptor(More)
The human signaling lymphocyte activation molecule (SLAM, also called CD150), a regulator of antigen-driven T-cell responses and macrophage functions, acts as a cellular receptor for measles virus (MV), and its V domain is necessary and sufficient for receptor function. We report here the generation of SLAM knockin mice in which the V domain of mouse SLAM(More)
BACKGROUND The balance between Th17 cells and regulatory T (Treg) cells has been shown to play an important role in the development of rheumatoid arthritis (RA). Recent studies have shown that treatment with abatacept (ABT) or tocilizumab (TCZ) affects Th17 and Treg cell populations. Although not unanimously accepted, several reports have shown that Treg(More)
Although the role of T cells in autoimmunity has been explored for many years, the mechanisms leading to the initial priming of an autoimmune T cell response remain enigmatic. The 'hit and run' model suggests that self-antigens released upon cell death can provide the initial signal for a self-sustaining autoimmune response. Using a novel transgenic mouse(More)
