The hydrophobic C terminus of pore-forming colicins associates with and inserts into the cytoplasmic membrane and is the target of the respective immunity protein. The hydrophobic region of colicin U of Shigella boydii was mutated to identify determinants responsible for recognition of colicin U by the colicin U immunity protein. Deletion of the tip of the hydrophobic hairpin of colicin U resul...
background: human immunodeficiency virus (hiv) makes infected cases prone to opportunistic infections like tuberculosis (tb) due to impaired immunity of the body, especially multi drug resistant (mdr) ones which are a major concern. with hiv outbreak starting late in the 20th century, the international health community is observing a huge rise in the incidence of this complex disease. herein, w...
BACKGROUND We have previously reported that an early initiation of highly active antiretroviral therapy (HAART) in HIV-1 vertically infected children enhanced the function of memory B-cells gained during childhood routine vaccinations. On the other hand, a significant waning of immunity was observed for patients with a late treatment. In this follow-up study, we report data from a sample of pat...
Anti-glomerular basement membrane (GBM) glomerulonephritis, which was among the earliest recognized human autoimmune diseases, is characterized by the presence of anti-GBM antibody. It has been a prototypical example of autoantibody-mediated autoimmune disease. However, decades of research on this disease, based either on clinical observations or experimental models, have revealed that T cell-m...
The tendency of certain individuals to repeated attacks of pneumonia has at times given rise to doubt whether acquired immunity to pneumonia exists. Considerable evidence, however, can be brought forward to show that a rather high degree of immunity to the pneumococcus follows an attack of pneumonia. The crisis itself is a striking expression of immunity. Furthermore, Dochez 1 has shown that th...
Active Immunity Produced by so Called Balanced or Neutral Mixtures of Diphtheria Toxin and Antitoxin
The foregoing and earlier data taken together demonstrate that an active immunity lasting several years can be produced in guinea-pigs, by the injection of toxin-antitoxin mixtures which have no recognizable harmful effect either immediate or remote. They also show, what might have been anticipated, that under the same conditions mixtures which produce local lesions and which, therefore, contai...
The article presents the materials of effect polyvalent inactivated culture vaccine against infectious rhi-notracheitis, viral diarrhea, parainfluenza-3, respiratory syncytial, rotavirus and coronavirus infection cattle "BolsheVak" on immunomorphogenesis in rabbits. It was found that double immunization with an interval 21 days allows for more active development cellular humoral immunity immuni...
