In recent years, with the rapid development of Chinas breeding industry, the weaning age of piglets is also in advance. The weaning time of piglets determines the number of piglets per year and the reproduction rate of sows. At the same time, the earlier weaning the piglets, the lower the production cost. However, early weaning of piglets will have a series of adverse effects on piglets. First of all, piglets will suffer from malnutrition due to early weaning, and their growth and development wi...

Neutrophils are the most abundant leukocytes in humans and among the first cells to arrive on the site of inflammatory immune response. Due to their key role in inflammation, neutrophil functions such as locomotion, cytokine production, phagocytosis, respiratory burst and release of extracellular traps are extensively studied. In the presentstudy, we present a simplified neutrophil isolation protocol which has excellent reproducibility and low cost. Taken together, our findings point to the fact...

Asthma is one of the most common chronic diseases worldwide affecting approximately 300 million individuals. Asthma or anaphylaxis are allergic diseases essentially characterized by eosinophilia and mast cells release histamine which is responsible for the production of IgE. Nevertheless, neutrophils are highly implicated and it is demonstrated in about 50% of asthma cases. Consecutive to bronchial allergen challenge for example, there is an influx of neutrophils in proximal and distal airways. ...

Rituximab, the monoclonal antibody against B lymphocyte protein CD20, is a major asset for treatment of diseases in which B CD20 cells are the foremost etiologic culprit. Based on observations that rituximab is capable to modulate immune responses the question if the drug may affect the capacity of human peripheral blood mononuclear cells (PBMC) for cytokine production was posed. The discovery of rituximab, a monoclonal antibody against B lymphocyte membrane protein CD20, contributed greatly to ...

The interaction between CD8 and HLA class I is largely monomorphic and of low affinity. Previous HLA mutation studies have indicated that manipulation of the affinity of this interaction can have dramatic biological effects. Reductions in CD8-HLA class I affinity can lead to inhibition of T cell mediated target cell killing, whilst modest affinity increases lead to enhanced target cell killing whilst retaining antigenic specificity. Here it is shown that target cells bearing a high affinity chim...

Inflammation is a complex biological response mediated by macrophages to protect the body from the pathogens and danger signals. The inflammatory response is initiated by priming, a process increasing the expression of inflammatory genes by extracellular pattern-recognition receptor (PRR)-mediated detection of pathogens, followed by triggering, a process detecting cytosolic pathogens by intracellular PRRs. Triggering induces the formation of intracellular PRR complexes called inflammasomes compo...

Polysaccharides consist of long chains of repeating sugars that are capable of multivalent cross-linking of BCR on the surface of polysaccharide-specific B cells.

Uridine cytidine kinase like-1 (UCKL-1) is a largely uncharacterized protein over-expressed in many tumor cells, especially in highly malignant, aggressive tumors. Sequence analysis indicates that UCKL-1 has homology to uridine kinases, enzymes that play a role in DNA and RNA synthesis and that are often up-regulated in tumor cells. Previous studies have shown that UCKL-1 is a substrate for natural killer lytic-associated molecule (NKLAM), an E3 ubiquitin ligase found in NK cell cytolytic granul...

Idiopathic rhinitis (IR), previously referred to as 'intrinsic rhinitis' or 'non-allergic perennial rhinitis', is a form of rhinitis that occurs without a known predisposing factor. In fact, IR is a subtype of non-allergic non-infectious rhinitis; the pathophysiology of IR has not been completely elucidated. Negative skin-prick test (SPT) along with the classical symptoms at the time of presentation may lead to misdiagnosis of vasomotor rhinitis. However, vasomotor rhinitis is a form of non-alle...
