2. 1. Bacterial toxins for cancer treatment

   Author : David Johansson; Parviz Behnam-Motlagh; Kjell Grankvist; Anders Johansson; Roger Henriksson; Bo Baldetorp; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alpha‐toxin; AC‐toxin; mesothelioma; lung cancer; glioma; breast cancer; caspases; MAP-Kinase; verotoxin‐1; cisplatin; apoptosis; Gb3; drug resistance; Clinical chemistry; Klinisk kemi;

   Abstract : Even though anti‐cancer chemotherapy has been continuously improved during the last decades. problems with adverse effects and drug resistance still constitutes a considerable obstacle and sets a demand for new effective treatment options. READ MORE

4. 2. Process Analytical Tools for the Monitoring and Characterization of Bacterial Toxins

   Author : Martin Hedström; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioteknik; Biotechnology; protein degradation; mass spectrometry; Bacterial toxins; Biosensor;

   Abstract : In the era of proteomics, glycomics and ultimately metabolomics, with constantly increasing knowledge regarding the human biosystem, the number of specialized therapeutic agents which will be developed against different diseases is predicted to be on the upswing. An increasing portion of these new drugs will, according to recent predictions (Labrou, 2003), be of proteinaceous origin produced according to biotechnological standards. READ MORE

5. 3. Genetic diversity of the heat labile (LT) and heat stable (ST) toxins of human enterotoxigenic Escherichia coli (ETEC): New insights into polymorphism, regulation, and gene transcription

   Author : Enrique Joffre; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ETEC; diversity; bacterial enterotoxins; polymorphism; gene regulation; gene transcription; Diarrhoeal disease; bacterial infection;

   Abstract : Infection with enterotoxigenic Escherichia coli (ETEC) is a leading cause of diarrhea in children in developing countries and travelers to endemic regions. ETEC is a diverse pathogen, with a wide range of virulence factors including enterotoxins and more than 25 identified colonization factors (CFs). READ MORE

6. 4. To defend or to offend? : Bacterial defence and competition systems

   Author : Danna Lee; Sanna Koskiniemi; Marjan van der Woude; Uppsala universitet; []
   Keywords : bacterial defence systems; bacterial competition systems; toxin-antitoxin systems; colicin; contact-dependent growth inhibition CDI ; type VI secretion system T6SS ; Rearrangement hotspot Rhs proteins; CRISPR; horizontal gene transfer; antibiotic resistance; Salmonella; Enterotoxigenic E. coli ETEC ; probiotics; synthetic biology.;

   Abstract : Bacteria are prokaryotic microorganisms that can be found in all niches of the biosphere. Bacteria must constantly evolve in order to survive and adapt to their environments. Defence systems and competition systems play a vital role in ensuring the survival of bacteria. READ MORE

7. 5. Effects of bacterial toxins on calcium homeostasis in renal inflammation

   Author : Tomas Söderblom; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Calcium (Ca2+) is a highly versatile ion used for intra- and inter-cellular signalling in eukaryotic cells, and numerous cellular events are regulated by alteration of the intracellular Ca2+ concentration. We hypothesized that bacterial virulence factors may alter the Ca 2+ homeostasis in epithelial cells such that the innate immune response is affected. READ MORE
