Råttan är en däggdjursart med en kort dräktighetstiden och föds därför mycket omogen. Den är vid födelsen naken, blind och döv och är helt beroende av sin moder för många funktioner, såsom näringstillförsel, termoreglering, urinering och tarmtömning. Under diperioden är råttans mag-tarmsystem och matsmältning helt anpassad till modersmjölkdieten. Bland annat är tarmens barriärfunktion omogen, vilk

The gene for an IgA-binding protein from a group A streptococcal strain was cloned and expressed in Escherichia coli. The IgA-binding protein, called protein Arp, was purified on IgA-Sepharose, allowing complete purification in a single step. Analysis of protein Arp by Western immunoblotting demonstrated a major IgA-binding band, with an apparent molecular weight of 42 kD. The purified protein was

Background: A significant proportion of patients with asthma have persistent symptoms despite treatment with inhaled glucocorticosteroids. Objective: We hypothesized that in these patients, the alveolar parenchyma is subjected to mast cell-associated alterations. Methods: Bronchial and transbronchial biopsies from healthy controls (n = 8), patients with allergic rhinitis (n = 8), and patients with

Group B Streptococcus (GBS) is a leading cause of invasive bacterial infections in human newborns. A key GBS virulence factor is its capsular polysaccharide (CPS), displaying terminal sialic acid (Sia) residues which block deposition and activation of complement on the bacterial surface. We recently demonstrated that GBS Sia can bind human CD33-related Sia-recognizing immunoglobulin (Ig) superfami

EndoS from Streptococcus pyogenes efficiently hydrolyzes the functionally important and conserved N-linked glycan of IgG in human blood. Repeated i.v. administration of EndoS in rabbits completely hydrolyzes the glycans of the whole IgG pool, despite the generation of anti-EndoS antibodies. EndoS administration had no apparent effects on the health of the animals. EndoS hydrolysis of the IgG glyca

This work presents ideas to underpin efforts to leverage the production of large volumes of agro-biomass and biofuels from transition economies in transition (EiTs) in Central and Eastern Europe with a key focus being co-benefits offered by agro-biofuel production. It departs in recognition of significant institutional barriers to establishment of dedicated plantings; the need for bioenergy within

Regular prophylactic treatment with factor VIII (FVIII) and factor IX (FIX) concentrates in hemophilia A and B, respectively, is introduced in early infancy and has resulted in dramatic improvement of the conditions. Recombinant FVIII and FIX concentrates have been available for > 25 years and have been modified and refined through the years; however, unfortunately frequent intravenous administrat

We have characterized 2 distinct mechanisms through which infectious agents may promote platelet adhesion and thrombus formation in flowing blood, thus contributing to the progression of disease. In one case, the process initiates when the integrin alpha(IIb)beta(3) mediates platelet arrest onto immobilized bacterial constituents that have bound plasma fibrinogen. If blood contains antibodies agai

Lymphocytes from human peripheral blood were separated by Countercurrent distribution (CCD) in a charged aqueous two-phase system composed of Dextran T 500 and polyethylene glycol 6000. Maximal responses to the T-cell mitogens phytohemagglutinin and concanavalin A were detected in a part of the distribution corresponding to the area where the highest percentage of E rosetting cells were seen. Anti

Protein ADP-ribosylation is a reversible post-translational modification that regulates important cellular functions. The identification of modified proteins has proven challenging and has mainly been achieved via enrichment methodologies. Random mutagenesis was used here to develop an engineered Af1521 ADP-ribose binding macro domain protein with 1000-fold increased affinity towards ADP-ribose. T
