The authors analyze their findings in the study on the effects of interferon preparations (immune gamma-interferon and recombinant alpha 2-interferon) on the ability of blood lymphocytes of dermatoses patients and normal subjects to enter the rosette formation. Preliminary cell treatment with gamma-interferon in vitro essentially influences lymphocytic rosette forming activity, the initial functional activity of cellular receptor system being of paramount importance here. gamma-interferon increased cellular rosette-forming activity and virtually did not influence the unchanged parameters in the patients with lowered values by spontaneous and early active E-RFC. Besides that immune interferon increased the count of 'heavy' rosettes detectable in spontaneous and active E-rosette formation. Recombinant alpha 2-interferon did not essentially alter the blood lymphocyte receptor system.

Background Aims: Hepatitis B virus (HBV) leads to severe liver diseases, such as cirrhosis and hepatocellular carcinoma. Identification of host factors that regulate HBV replication can provide new therapeutic targets. The discovery of sodium taurocholate cotransporting polypeptide (NTCP) as an HBV entry receptor has enabled the establishment of hepatic cell lines for analyzing HBV infection and propagation.

Tumour necrosis factor (TNF) is one of the most pivotal factors of the TNF family and plays an essential biological role in immunity. However, the antibacterial function and mechanism of TNFα in teleosts are relatively poorly understood. In this study, a novel TNFα from Trachinotus ovatus (TroTNFα) was characterized.

Background: C-type lectin (CTL) plays an important act in parasite adhesion, host's cell invasion and immune escape. Our previous studies showed that recombinant Trichinella spiralis C-type lectin (rTsCTL) mediated larval invasion of enteral mucosal epithelium. The aim of this study was to investigate protective immunity produced by vaccination with rTsCTL and its effect on gut epithelial barrier function in a mouse model.

Erdheim-Chester Disease is a rare systemic xanthogranulomatous infiltrating disease, characterized by lipid-laden histiocytes accumulating in various organs and almost always in bones. Etiology of the disease is still unknown. It may involve various organs and systems, such as musculoskeletal, cardiac, pulmonary, renal, gastrointestinal and central nervous system (CNS) as well as the skin.
