The peptidoglycan (PGN)-recognition protein LF (PGRP-LF) is a specific negative regulator of the immune deficiency (Imd) pathway in Drosophila. We determine the crystal structure of the two PGRP domains constituting the ectodomain of PGRP-LF at 1.72 and 1.94 Å resolution. The structures show that the LFz and LFw domains do not have a PGN-docking groove that is found in other PGRP domains, and t...
Nucleotide oligomerization domain-containing protein 2 (Nod2), an innate immune receptor, recognizes bacterial cell-wall peptidoglycan (PGN), the minimum ligand of which is muramyl dipeptide (MDP). Enzymatic digestion of PGN appears to be important for Nod2 recognition. PGN is degraded by muramidase or glucosamidase through a process that produces two types of glycan sequence; glycans containin...
Recent improvement in technologies for measuring individual feed intake has made possible the collection of data suitable for breed-wide genetic evaluation. The goals of this research were to estimate genetic parameters for components of feed efficiency and develop a prototype system for conducting a genetic evaluation of Angus cattle for feed intake. Weaning weight (WWT), postweaning BW gain (...
The innate immune system coordinates the inflammatory response to pathogens. To do so, its cells must discriminate self from non-self utilizing receptors that identify molecules synthesized exclusively by microbes. Toll- like receptors have a crucial role in the detection of microbial infection in mammals and insects. In mammals, they have evolved to recognize conserved products unique to micro...
Peptidoglycan (PGN) recognition proteins (PGRPs) are important pattern recognition receptors (PRRs) involved in immune defense against bacterial infections. In this study, a short PGRP (termed AdPGRP-S1) was cloned and functionally characterized from Chinese giant salamander (Andrias davidianus), the largest extant urodela amphibian species. AdPGRP-S1 was 184 aa in length and shared 38.7%-54.9%...
Extracellular and intracellular recordings from slices of ferret dorsal lateral geniculate nucleus (LGNd) at postnatal ages P10-53 were performed to examine the postnatal development of spindle waves and the ability of block of GABAA receptors to alter these spindle waves into a slower, synchronous oscillation. As in prior studies in the adult, intracellular and extracellular recordings at ages...
Aberrant extracellular matrix (ECM) remodeling in sebaceous glands and pilosebaceous units in the skin is associated with scar formation under acne conditions. To investigate the involvement of Propionibacterium acnes (P. acnes), a Gram-positive anaerobic microbial species, in ECM remodeling in sebaceous glands and pilosebaceous units, we examined the effects of P. acnes culture media, formalin...
The interaction of two populations of integrate-and-fire-or-burst neurons representing thalamocortical cells from the dorsal lateral geniculate nucleus (dLGN) and thalamic reticular cells from the perigeniculate nucleus (PGN) is studied here using a population density approach. A two-dimensional probability density function that evolves according to a time-dependent advection-reaction equation ...
Deregulation of soluble apoptosis stimulating fragment (sFas) plays an important role in glomerulonephritis (GN). The study assed the influence of immunosuppressive treatment on serum and urine sFas in patients with proliferative (PGN) and non-proliferative (NPGN) GN, and evaluated the potential of sFas measurements in predicting outcomes. Eighty-four patients with GN (45 males and 39 females) ...
INSULIN RESISTANCE IS A LEADING CAUSE of type 2 diabetes, and inflammation has emerged as an important mediator between obesity and insulin resistance. The links between immunity and metabolism are extensive and have been proposed to originate from structures in lower organisms that are responsible for both danger and metabolite sensing (6). This has introduced the interesting concept that comm...
