Salmonella Typhimurium (S.Tm) is a common cause of self-limiting diarrhea. The mucosal inflammation is thought to arise from a standoff between the pathogen's virulence factors and the host's mucosal innate immune defenses, particularly the mucosal NAIP/NLRC4 inflammasome. However, it had remained unclear how this switches the gut from homeostasis to inflammation. This was studied using the str...
This research applied multiple endmember spectral mixture analysis (MESMA) onto a Hyperion Earth Observer 1 (EO-1) hyperspectral image of the channeled scablands of eastern Washington. The goal of this research was to quantify sub-pixel abundances of three endmembers: sagebrush, soil, and grass. Quantification of land cover abundance would greatly benefit wildlife habitat conservation, rangelan...
The innate immune system is the first line of defense against microorganisms and is conserved in plants and animals. The nucleotide-binding domain, leucine rich containing (NLR) protein family is a recent addition to the members of innate immunity effector molecules. These proteins are characterized by a central oligomerization domain, termed nucleotide-binding domain (NBD) and a protein intera...
Aerial and satellite imagery are widely used to assess the severity and impact of wildfires. Light detection and ranging (LiDAR) is a newer remote sensing technology that has demonstrated utility in measuring vegetation structure. Combined use of imagery and LiDAR may improve the assessment of wildfire impacts compared to imagery alone. Estimation of tree mortality at the plot scale could serve...
Agents that activate dendritic cells are essential components for vaccines and can be conceptualized as molecular adjuvants. Other molecular adjuvants affect downstream factors that shape the resulting immune response. This review provides a compendium of recently studied molecular adjuvants, focusing on CD8+ T cell responses, which have important roles in HIV vaccines. Reference is also made t...
NLR family apoptosis inhibitory proteins (NAIPs) belong to both the Nod-like receptor (NLR) and the inhibitor of apoptosis (IAP) families. NAIPs are known to form an inflammasome with NLRC4, but other in vivo functions remain unexplored. Using mice deficient for all NAIP paralogs (Naip1-6(Δ/Δ)), we show that NAIPs are key regulators of colorectal tumorigenesis. Naip1-6(Δ/Δ) mice developed incre...
Recently, a spinal muscular atrophy (SMA) determining gene, termed survival motor neuron (SMN) gene, has been isolated from the 5q13 region and found deleted in most patients. A highly homologous copy of this gene has also been isolated and located in a centromeric position. We have analyzed 158 patients (SMA types I-IV) and found deletions of SMN exon 7 in 96.8%. Mutations other than gross del...
Satellite data have been widely used in the detection of vegetation area changes, however, the lack of historical training samples seriously limits detection accuracy. In this research, an iterative intersection analysis algorithm (IIAA) is proposed to solve this problem, and employed to improve the change detection accuracy of Phragmites area in the Detroit River International Wildlife Refuge ...
Inhibitors of apoptosis (IAPs) are a diverse group of signaling molecules that function in a wide range of cellular roles, from the inhibition of caspases to the promotion of cell-cycle progression. These diverse functions may well be linked to the many different domains that are contained within different proteins in the family. IAP family members were first described as inhibitors of apoptosi...
NAIP CIIA HET-E and TP1 (NACHT) family proteins are involved in sensing intracellular pathogens or pathogen-derived molecules, triggering host defense responses resulting in caspase-mediated processing of proinflammatory cytokines and NF-kappaB activation. Caspase-associated recruitment domain, leucine-rich repeat, and NACHT-containing protein (CLAN), also known as ICE protease-activating facto...
