Lactobacilli in the normal microbiota and probiotic effects of Lactobacillus plantarum
(2010-01-11)Lactobacilli colonise most adult individuals and are also frequently used as probiotics, i.e. bacteria which possibly have health promoting effects when ingested. In this thesis, the intestinal Lactobacillus microbiota was ... -
LEUKOCYTE RECRUITMENT TO HUMAN GASTROINTESTINAL TISSUES - STUDIES IN H. PYLORI-INDUCED GASTRITIS AND COLON ADENOCARCINOMAS
(2010-11-19)Chronic inflammation is a major pathological basis for tumor development and two examples are H. pylori infection of the stomach mucosa and inflammatory bowel disease, which are strongly associated with gastric and colon ... -
Lipooligosaccharide and Cytolethal distending toxin of Haemophilus ducreyi and antibody responses
(2010-03-31)The Gram-negative bacterium Haemophilus ducreyi causes chancroid, a sexually transmitted infection characterized by persistent ulcers on genitals. The disease is prevalent in developing countries and facilitates transmission ... -
Liposarcomas - proliferation, senescence and the role of DDIT3
(2014-02-28)Lipomatous tumors comprise benign and malignant forms called lipomas and liposarcomas. Myxoid/round cell liposarcoma (MLS/RCLS) is the second most common liposarcoma and is characterized by the fusion oncogenes FUS-DDIT3 ... -
lnclusion body myositis - Genetic, clinical, and epidemiological aspects
(2023-05-16)The inflammatory myopathy inclusion body myositis (IBM) is characterized by progressive muscle weakness and dysphagia in individuals over 45 years of age. Muscle biopsy shows inflammatory infiltrates, vacuoles with protein ... -
lntestinal microenvironment, epithelial barrier interactions and human milk oligosaccharide supplementation in irritable bowel syndrome
(2022-05-19)Alterations of the microbiota-host interactions at the mucosal border may be of importance in symptom generation in irritable bowel syndrome (IBS), a disorder of gut-brain interaction. Hence, microbiota-targeted interventions ... -
Lung-resident, M2e-specific CD4 T cells critically protect during influenza infection
(2018-11-22)Memory CD4+ T cells are a critical component of the adaptive immune response to fight infection. However, current vaccines against influenza only focus on the other arm of adaptive immunity—triggering B cells to produce ... -
Lyme Neuroborreliosis - Diagnosis and Treatment
(2014-05-05)Lyme neuroborreliosis, the infection of the nervous system by the tick-borne bacterium Borrelia burgdorferi, is a common infection in the temperate parts of the Northern hemisphere. Manifestations of the disease include ... -
Macrophages in Crohn's Disease: lnnate immune cellular and molecular mechanisms driving intestinal inflammation and fibrosis
(2023-11-22)Macrophages and their interactions with the lamina propria and luminal microenvi-ronment are crucial in the pathogenesis of Crohn´s disease (CD), a chronic inflamma-tory disease with a strong inflammatory innate immune ... -
Mass spectrometric analyses of proteoglycans - Novel tools for studying prohormones in insulin-producing cells
(2020-12-15)Proteoglycans (PGs) are proteins that carry one or more negatively charged glycosaminoglycan (GAG) chains. Proteoglycans have been identified in essentially all multicellular organisms, and are implicated in a wide range ... -
Mass spectrometry for comparative proteomics of degenerative and regenerative processes in the brain
(2006-12-01)Biological processes involve changes at the protein level. Proteomics aims to determine protein changes from a normal state, to measure for instance recovery or disease progression. Mass spectrometry is the most important ... -
Measurement of sensitivity to DNA damaging agents
(2017-08-18)There is a large inter-individual variation in intrinsic sensitivity in patients receiving treatment with DNA damaging agents. Cancer therapy exemplifies this problem where patients experience varying degree of normal ... -
Measurements of the DNA double-strand break response
(2012-09-25)Radiotherapy and some chemotherapeutic drugs kill cancer cells by induction of the extremely toxic DNA double-strand breaks (DSBs). Measurements of the DSB response in patients during therapy could allow personalized ... -
Mechanisms of dendritic cell maturation induced by intracellular bacteria infection
(2007-10-02)Dendritic cells (DCs) are essential for the development of an immune response against pathogens such as Listeria monocytogenes and Salmonella typhimurium. This is mostly because of their unique capacity to stimulate naïve ... -
Mechanisms of leukemia-induced immunosuppression
(2012-05-25)This thesis aimed to define the role of reactive oxygen species (ROS), produced by the NADPH oxidase of myeloid cells, in the regulation of lymphocyte function with focus on ROS-induced dysfunction of natural killer (NK) ... -
Mechanistic studies of the adjuvant effects of CTA1-DD and the native cholera toxin: Impact of cell targeting and tissue localization
(2012-05-15)Vaccines are the most effective means of preventing infectious diseases and improving global health. However, few vaccines have successfully been developed for protection at mucosal surfaces where most pathogens gain access. ... -
Mediator and cell cycle regulation
(2015-11-04)The multiprotein Mediator complex is an evolutionarily conserved coregulator of eukaryotic transcription. Mediator functions as a bridge between gene-specific transcription factors and the RNA polymerase II transcription ... -
Mediator and its role in non-coding RNA and chromatin regualtion
(2014-05-15)Mediator is a multiprotein complex required for the regulation of RNA Polymerase II (Pol II) transcription. Mediator transmits regulatory signals from activators and repressors to the Pol II machinery at the promoter, but ... -
Methods for evaluation of early bone healing at titanium implants
(2008-10-03)Titanium has for a long time been the implant material of choice when in need for abilities as strength, biocompatibility and stability. Although numbers of studies have been made, little is known about the early events ... -
Microbiota of the alimentary tract of children - implications for allergy and inflammatory bowel disease
(2014-09-19)Allergy, which is the most common chronic disease in Swedish children and adolescents, is associated with a high standard of living and Western lifestyle. According to the hygiene hypothesis, allergy is due to inadequate ...
