Natural Autoantibodies: Origin, Function And Utility For Diagnosis Of Disease, Abhirup Sarkar Aug 2019

Natural Autoantibodies: Origin, Function And Utility For Diagnosis Of Disease, Abhirup Sarkar

Graduate School of Biomedical Sciences Theses and Dissertations

Autoantibodies (aAbs) by the simplest definitions have been described as antibodies against self-antigens and were exclusively associated with autoimmune diseases. Eventually, studies demonstrated that they are abundant in the blood of all human sera, regardless of age, gender, or the presence or absence of disease, and were thus named as ‘natural autoantibodies’. The underlying reason for their ubiquity has remained elusive, but we have hypothesized that they are responsible for clearing blood-borne cell and tissue debris generated under conditions of health and disease. To test this, we chose to use two widely different disease model systems, namely neurodegenerative diseases and …

Research outputs 2014 to 2021

Detection of HFE Haemochromatosis (HH) is challenging in the absence of clinical features. HH subjects have elevated erythrocyte parameters compared to those without HH, but it remains unclear how this could be applied in clinical practice. Thus, we determined the sensitivity, specificity and clinical utility of erythrocyte parameters in 144 HH subjects with (n = 122) or without (n = 22) clinical and/or biochemical expression of iron overload, 1844 general population controls, and 700 chronic disease subjects. For both expressing and non-expressing HH subjects, the mean pre- and post-phlebotomy values of mean cell volume (MCV) and mean cell haemoglobin (MCH) …


Understanding Pseudomonas Aeruginosa Alginate Regulation And Its Link To Chronic Lung Infections In Cystic Fibrosis Patients, Roy Al Ahmar Jan 2019

Understanding Pseudomonas Aeruginosa Alginate Regulation And Its Link To Chronic Lung Infections In Cystic Fibrosis Patients, Roy Al Ahmar

Theses, Dissertations and Capstones

Cystic Fibrosis (CF) is a genetic disorder caused by mutations in the gene encoding Cystic Fibrosis Transmembrane Conductance Regulator (CFTR). This disorder results in thick lung secretions which compromise the patient’s immune system. Chronic lung infections with Pseudomonas aeruginosa biofilms is a major factor that contributes to poor outcome for clinical treatment. The overall hypothesis of this dissertation is that small colony variant and pyrimidine biosynthesis are linked with biofilm formation, alginate production is dependent on MucA proteolysis, rifaximin can be repurposed to treat biofilm infection and multiplex PCR can be used to rapidly measure the bacterial cell density in …
