Host molecular determinants of toxoplasma gondii dissemination
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2014-10-31)Humans and animals acquire the parasite Toxoplasma gondii through contaminated food or water, upon which the parasite rapidly disseminates in the host. In immunocompetent individuals, this acute phase is transient and leads ... -
Mast cell activation disorders : a liaison between anaphylaxis and mastocytosis
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2014-10-14)The term mast cell activation disorders (MCAD) comprises a broad spectrum of heterogeneous conditions, such as mastocytosis, characterized by inappropriate mast cell activation/accumulation. The patients present with protean ... -
A battle between host and pathogen : the innate immune response and enterovirus evasion strategies
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2014-09-18)Infections with Coxsackieviruses are common and in most cases the infection is asymptomatic and efficiently cleared. On rare occasions, however, an infection can lead to severe diseases including myocarditis, hepatitis and ... -
Immune repertoire diversity in allogeneic stem cell transplantation and its implications for infections and the graft versus leukemia effect
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2014-08-29)The beneficial graft versus leukemia effect (GVL) and its detrimental counterparts, graft versus host disease (GVHD) and susceptibility to infections, are all coupled to a multitude of events during the immune reconstitution ... -
Quantitative echocardiographic methods for patients with acute coronary syndrome
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2014-07-09)Background: The aim of this thesis was to evaluate two diagnostic and two prognostic quantitative echocardiographic methods for patients with acute coronary syndrome (ACS). Methods: Velocity tracking (VeT) presents ... -
Clinical and pathophysiological aspects of sepsis
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2014-03-14)Severe sepsis and septic shock represent challenging problems for the health care system. Despite adequate antibiotics and modern intensive care, severe sepsis is associated with a substantial mortality rate of around 30%, ... -
Interactions between enteroviruses and the host : implications for type 1 diabetes
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2014-02-28)Type 1 diabetes (T1D) is a disease that results after a selective destruction of the insulin-producing β-cells in the pancreas. The lack of β-cells renders T1D patients completely unable to synthesize and secrete insulin, ... -
The ontogeny and regulation of human natural killer cells
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2014-02-14)Natural Killer (NK) cells are members of the innate lymphoid cell (ILC) family and take part in the detection and eradication of virus-infected and transformed cells. In this thesis, together with my colleagues I have ... -
Molecular basis for enhanced T-cell recognition and cross-reactivity
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2013-12-20)T cells of the adaptive immune system recognize and kill infected cells by interacting with pathogenic peptides displayed on major histocompatibility complexes (MHC) through its T-cell receptor (TCR). TCR interactions with ... -
Specific T- and B-cell responses against human cytomegalovirus after hematopoietic stem cell transplantation
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2013-11-21)Human cytomegalovirus (CMV) remains an important complication in allogeneic hematopoietic stem cell transplantation (HSCT). CMV-reactivation may lead to CMV-disease associated with high morbidity and mortality in patients ... -
Studies of immune response in human tuberculosis
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2013-11-21)TB (tuberculosis), caused by Mycobacterium tuberculosis (Mtb), continues to be a world-leading killer and a serious global health problem primarily affecting poor people in many developing countries. The difficult situation ... -
Asthma and allergy in teenagers and young adults, risk-factors and T-cell regulation
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2013-11-15)Asthma is one of the most common chronic diseases among teenagers and young adults. The prevalence of asthma among young adults in Sweden is approximately 7-10%. Despite this, only a limited number of studies have focused ... -

(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2013-11-14)Liver disease, mainly due to hepatitis C virus (HCV) infection, is a leading cause of death in HIV positive patients with access to antiretroviral therapy (ART). HCV treatment, which can prevent long-term complications of ... -
Diagnostic and prognostic markers in sepsis
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2013-11-01)Sepsis is a life-threatening disease affecting millions of people globally. The more severe forms are considered to be a consequence of an unbalanced systemic inflammatory response to infection, causing organ dysfunction, ... -
Assessment of patients with symptoms suggestive of acute coronary syndrome : the use of high sensitive cardiac troponin T and a risk score
