PGRP-S (Tag7) is an innate immunity protein involved in the antimicrobial defense systems, both in insects and in mammals. We have previously shown that Tag7 specifically interacts with several proteins, including Hsp70 and the calcium binding protein S100A4 (Mts1), providing a number of novel cellular functions. Here we show that Tag7–Mts1 complex causes chemotactic migration of lymphocytes, with NK cells being a preferred target. Cells of either innate immunity (neutrophils and monocytes) or acquired immunity (CD4+ and CD8+ lymphocytes) can produce this complex, which confirms the close connection between components of the 2 branches of immune response. 相似文献

The detection rate of IgM, specific to cytomegalovirus (CMV), in the umbilical blood was 2.0 +/- 1.8% in infants with antenatal complications in their medical history, 8.9 +/- 1.8% in hospitalized infants aged 7 days to 6 months; simultaneously, such IgM proved to be absent in healthy infants of the same age. The maximum primary detection rate of CMV-specific IgM in hospitalized infants was registered at the age of 1.5-4 months and the minimum detection rate, at the age of 6 months, as well as at the age of 1 month and younger. In sick infants aged 0-6 months CMV-specific IgM were detected, as a rule, for 2-4 weeks. 86% of infants with CMV-specific IgM detected in their blood were found to have cytomegaloviremia; in 80% of patients the virus was excreted with saliva and in 50% the virus was detected in blood plasma. 相似文献

A study was made of the adjuvant effect of the mouse tumor necrosis factor alpha (mTNF alpha) on DNA immunization against the herpes simplex virus type 1 (HSV1). The HSV1 gD gene (pDNAgD) served as an immunogen; mTNF alpha or its gene cloned in an eukaryotic expression vector (pDNAmTNF) were used to modulate the immune response. Double immunization with pDNAgD led to a sixfold increase in the in vitro T-cell response, a high (1:2000) titer of anti-HSV1 antibodies (including virus-neutralizing antibodies), an increase in IgG2a/IgG1 (suggesting a shift of the immune response to the Th1 type), and no change in CD4/CD8 T-cell ratio. A single injection of mTNF alpha along with inactivated HSV1 allowed a twice higher antibody titer and a fourfold higher T-cell response as compared with immunization with HSV1 alone. Double immunization with both pDNAgD and pDNAmTNF increased the titer of anti-HSV1 antibodies and the T-cell response by factors of 8 and 1.5, respectively, as compared with immunization with pDNAgD alone. However, the protective effect was significantly lower with the two plasmids than with pDNAgD (73 vs. 100%). Thus, DNA immunization with pDNAgD induced both B- and T-cell responses and completely protected mice from a lethal doze of HSV1. The adjuvant properties of mTNF alpha and pDNAmTNF need further investigation. 相似文献

The results of the clinical trials of human recombinant interferon alpha-2 (reaferon) make it possible to come to the conclusion that the preparation is well-tolerated and produces a pronounced therapeutic effect in a number of viral and oncological diseases. The Pharmacological Committee of the USSR has recommended reaferon for use in acute hepatitis B, hairy cell leukemia, renal cancer at stage IV, disseminated sclerosis, ocular herpes. The use of reaferon has been found to be promising in the treatment of papillomatosis of the larynx, Kaposi's sarcoma, mycosis fungoides, chronic myeloleukemia. 相似文献

One hundred and thirty six Lactobacillus strains isolated from poultry and 23 Lactobacillus strains isolated from long-living persons were tested for their antibiotic sensitivity. Occurrence of some type determinants of resistance to aminoglycoside antibiotics and tetracyclines in the Lactobacillus strains resistant to these antibiotics was studied. The majority of the strains from the both collections were resistant to aminoglycosides (73 and 79 per cent, respectively). The isolates from the poultry were characterized by multiple resistance. The isolates from the long-living persons were most frequently resistant to one of two antibiotics. All the tested Lactobacillus strains isolated from the long-living persons were sensitive to tetracyclines. The species composition of the isolates was different. The antibiotic-resistant strains were detected in all the species involved in the study. By hybridization of Lactobacillus colonies with the probes containing various genes of the resistance it was shown that in 14 per cent of the antibiotic-resistant strains belonging to Lactobacillus the antibiotic resistance was controlled by the genes homologous to resistance genes widely distributed in gramnegative organisms. This indicated a possible wide exchange and heterologous expression of the antibiotic resistance determinants between microorganisms of various taxonomic groups. 相似文献

The preferential interactions of alpha-interferon (alpha-IFN) with delta and mu opiate receptors were studied. alpha-IFN (specific antiviral activity 2 X 10(3) U/mg protein) was shown to inhibit in the competitive manner 3H-naloxone and 3H-D-ala2, D-leu5-enkephalin (3H-DADL) specific binding to opiate receptor subpopulations. alpha-IFN was much more effective in decreasing 3H-DADL than 3H-naloxone binding in opiate receptors: K1 values averaged 160 +/- 30 and 1150 +/- 80 U/ml, respectively. IFN effective concentrations inhibiting 50% of 3H-naloxone opiate receptor binding in the absence or presence of 100 mmol/l NaCl were similar, and the "sodium shift" value was equal to 1. The independence of alpha-IFN activity of the presence of NA+ cations suggests the antagonist character of alpha-IFN interaction with opiate receptors. Thus, alpha-IFN employed appears to be an alpha-selective ligand displaying the in vitro properties of "pure" morphine antagonists. 相似文献

The work presents data on growing Rickettsiella phytoseiuli in the SM IMV-72 medium which is used for cultivation of phytopathogenic mycoplasmas. Rickettsiella was observed till the 66th day in the primary cultures and till the 16th day after the first passage. Binary division of the cells has been found only in the primary cultures; a complex cycle of the Rickettsiella development ceased at the stage of formation of the crystal-forming cells. Attempts to passivate Rickettsiella were failure. 相似文献
