worldwide (4,7,12,17,19). The serological clarification of Salmonella serovars may be determined by commercially accessible polyclonal and monoclonal antibodies (MAbs), which detect antigens characteristic to a particular serovar (7,18). A bacterium serovar is established by somatic, flagellar, and capsular antigens present in the cell walls (6,7,12,19). Belonging to the Enterobacteriaceae family S. Typhimurium is a gram-negative rod flagellated, non-sporing, catalase-positive,…

chemicals, and infections. While the genetic factors include Human leukocyte antigen (HLA) gene, cytotoxic T lymphocyte antigen 4 (CTLA4) gene, protein tyrosine phosphatase nonreceptor-type 22 (PTPN22) gene, vitamin D receptor gene, and cytokine genes. Lastly,…
according to the guidelines of the Dutch Federation of Medical Research Associations. Quadruple fluorescent and enzymatic immunostaining of tumor infiltrating lymphocytes and their ligands had been performed using 4 µm sectioned fixed tissues. A citrate antigen was silver stained with anti-cytokeratin AE1/AE3 antibody (IgG1), followed by a mixture of antibodies ab828 (polyclonal, anti-CD8), HNK-1 (IgM, anti-CD57), and 4B11 (IgG2b, anti-CD8) were added to a slide of the fixed tissue. This…
specific autoantibodies in preclinical and clinical studies, it is still a less explored area of autoimmunity. In this review, we first discuss how the autoimmunity is triggered in TBI and summarize the current self-antigens. We further focus on the TBI-generated brain specific antigens based on animal research and clinical studies as well as the possibility strategy of biofluid-based TBI diagnosis. Last we also discuss the characteristics of these autoantibodies post…
via injection, contains the parts of Neisseria meningitides (which cannot cause infection but which encourages the body to fight the bacteria through building up antibodies (substances the body produces to fight disease). The antibodies combat the antigens (a toxin which induces…
CHAPTER I INTRODUCTION Background and Significance Sickle cell disease (SCD) is an inherited red blood cell disorder that is present at birth and is often more prevalent amongst African Americans.1 In order to inherit SCD, a person must inherit two abnormal hemoglobin genes, one from each parent. Hemoglobin is a protein found in red blood cells that is responsible for absorbing oxygen in the lungs and transporting it throughout the body.13 Proteins typically have four levels of structure:…
Pathophysiology of MS MS is characterized by CNS inflammation, demyelination, axonal injury and neurodegeneration. Current consensus dictates that it is an autoimmune disorder. However, to date, no specific precipitating antigen has been found. A general consensus is that MS begins with the formation of acute inflammatory lesions characterized by breakdown of the blood-brain barrier (BBB). These lesions are often clinically ‘silent’ and have been estimated to be about ten times more frequent…
Involving the use of living organisms like bacteria in industrial processes due to their natural metabolic capabilities are known as biotechnology. They are used a several ways such as manufacturing of foods, cosmetic products and production of antibiotics, probiotics, drugs, vaccines, insecticides, and enzymes. In addition, they are also being widely used in the genetic engineering. Nowadays, bacteria are commonly used in the food industry for the manufacture of dairy products such as cheese,…
Functions of protein TP53 TP53 has a general name called tumor suppressor protein p53. Tp53 has many names such as phosphoprotein p53, cellular tumor antigen p53, tumor suppressor p53, antigen NY-CO-13, or transformation-related protein 53 (TRP53). Also, TP53 has also been referred to as the guardian of the genome [19]. In 1979, scientists first observed the gene by using SDS-PAGE and found it has a size of about 53-kilodalton (kDa). The location of the TP53 gene is at chromosome 17, at…
