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

One hundred eighty nine children with acute bronchopulmonary infectious pathological processes were examined bacteriologically and serologically for typical pneumotropic pathogens, 47 of them being as well examined for atypical organisms. Microbial associations mainly with Mycoplasma and Pneumocystis and to a lesser extent with Chlamydia were isolated from the majority of the children. Reactivation of the cytomegalovirus infection was observed in 25 per cent of the children. Pneumonia and bronchitis due to Mycoplasma pneumoniae either as a monoagent or in associations were mainly stated in children over 7 years of age. No significant changes between the indices of the infection due to a definite organism and the active progression of the infectious process of the same etiology were revealed, though in the cases of chlamydiosis the changes reached almost 10 per cent. In cases of acute bronchitis and pneumonia the chlamydial or cytomegalovirus infection could be assumed to be of the persisting nature, mainly acute in cases of pneumococcal infection, mixed in cases of hemophilic or pneumocystic infection, primary contamination with a tendency to prolonged in cases of mycoplasmic infection. The findings of the examination and the clinical and anamnestic data showed that the clinical picture of acute pneumonia had specific features associated with the supposed etiological agents, still it could change under the action of associations of pneumotropic pathogens. 相似文献

In cells of human embryo skin--muscle tissue transformed by the Rouse sarcoma virus (23rd cell line) and polyoma virus (P-2 cell line), the mitotic activity was 48 0/00 for 23rd line, 51 0/00 for P-2 line as against 28 0/00 in the control cells. The transformed cells possessed greater amounts of RNA and DNA and protein--bound SH-groups, different forms of glycogen deposits, as well as higher acid phosphatase enzyme activities; there was practically no difference in acid mucopolysaccharide content or NAD-H2-diaphorase and succinate dehydrogenase activities. 相似文献

Data on HIV infection in pregnant women in Chelyabinsk are presented. Starting from 1999, a considerable rise in the number of HIV-infected persons was registered in this city. The social and epidemiological characteristics of HIV-infected pregnant women, as well as the main routes and factors of the infective agent transmission, are given. Relationship between the spread of HIV-infection and drug addiction is revealed. The occurrence of different opportunistic infections in HIV-infected pregnant women is determined. 相似文献

The examination of 112 hematological patients with diagnosed acute and chronic leucosis, lymphoma, myeloma, anemia, melanoma and other diseases revealed not a single subject among these examinees in whom no markers of opportunistic infections were detected. Low titers of antibodies to Pneumocystis carinii, cytomegalovirus (CMV), Epstein-Barr virus (EBV) were noted in 42%, 46.4% and 40.2% of examinees, respectively. Markers of acute diseases, such as class IgM, IgG antibodies in high titers, as well as P.carinii, CMV, EBV antigens, were detected in 37.5%, 30.4% and 22.3% of patients of a hematological hospital. In the group of comparison (donors) these figures were, respectively, 15.3%, 2.4% and 6.9%. The signs of monoinfection were detected in 11.6% (pneumocystosis), in 10.7% (CMV infection) and in 14.3% (EBV infection), while the markers of two infections, EBV infection and pneumocystosis, were detected in 9.8%, EBV and CMV infections in 11.6%, pneumocystosis and CMV infection in 14.3%; mixed contamination with all three infective agents was detected in 12.5% of the patients. 相似文献

We present an efficient computational architecture designed using supervised machine learning model to predict amyloid fibril
forming protein segments, named AmylPepPred. The proposed prediction model is based on bio-physio-chemical properties of
primary sequences and auto-correlation function of their amino acid indices. AmylPepPred provides a user friendly web interface
for the researchers to easily observe the fibril forming and non-fibril forming hexmers in a given protein sequence. We expect that
this stratagem will be highly encouraging in discovering fibril forming regions in proteins thereby benefit in finding therapeutic
agents that specifically aim these sequences for the inhibition and cure of amyloid illnesses.
