Mot smartare cellgiftsbehandling: Att förebygga behandlingsresistens vid äggstockscancer Äggstockscancer är den dödligaste gynekologiska cancertypen och kräver alltför många liv eftersom tumörer ofta blir resistenta mot behandling – särskilt mot cisplatin, vårt främsta försvar. För att rädda fler liv måste vi förstå hur denna resistens utvecklas och hur vi kan överlista den. I mitt examensarbete Ovarian cancer is the deadliest gynaecologic malignancy, with most patients diagnosed at an advanced stage and facing poor long-term survival. Resistance to cisplatin-based chemotherapy is a major clinical obstacle, yet its proteomic drivers remain poorly defined. In this study, I applied data-independent acquisition mass spectrometry with DIA-NN data processing to analyse one parental and two cis

Background. We evaluated the impact of a quadrivalent human papillomavirus (HPV) vaccine on infection and cervical disease related to 10 nonvaccine HPV types (31, 33, 35, 39, 45, 51, 52, 56, 58, and 59) associated with >20% of cervical cancers. The population evaluated included HPV-naive women and women with preexisting HPV infection and/or HPV-related disease at enrollment. Methods. Phase 3 effic

Popular Abstract in Swedish Grupp B streptokocker (GBS; Streptococcus agalactiae) är den vanligaste orsaken till livs-hotande infektioner hos nyfödda barn. Enbart i USA orsakar GBS ~10 000 fall av meningit (hjärnhinneinflammation), pneumoni (lunginflammation) och sepsis (blodförgiftning) varje år. Infektionerna har hög dödlighet och en stor del av de barn som överlever infektionerna får bestående Streptococcus pyogenes (group A streptococcus) and the group B streptococcus (GBS) are two important human pathogens that cause different types of diseases and express different surface structures implicated in virulence. This thesis focuses on several surface proteins expressed by these pathogens, analyzing the biological function of these proteins and their ability to elicit protective immunity.

Popular Abstract in Swedish Människan lever inte bara själv, utan tillsammans med en mängd bakterier som lever i kroppen. Större delen av dessa lever i tjocktarmen. Dessa organismer är viktiga för vår hälsa. De stimulerar immunförsvaret, sänker pH i tarmen och gör det ogynnsamt för sjukdomsframkallande bakterier att växa till. Bakterierna lever i symbios med oss och med varandra. Förändringar i taThe human gut flora is important for our well-being. The gut bacteria are able to degrade and metabolize complex carbohydrates. Examples of such carbohydrates are β-mannans. β-Mannans consist of a backbone of β-1,4-linked mannose units and are present in e.g. the endosperm of legumes such as guar or carob. The composition of the β-mannan varies with the plant source. Carob and guar β-mannans are s

Long-term tobacco smokers with chronic obstructive pulmonary disease (COPD) or chronic bronchitis display an excessive accumulation of neutrophils in the airways; an inflammation that responds poorly to established therapy. Thus, there is a need to identify new molecular targets for the development of effective therapy. Here, we hypothesized that the neutrophil-mobilizing cytokine interleukin (IL)

Hemicelluloses account for 25-30% of total wood dry weight. Mannan-based polysaccharides are the major component of softwood hemicelluloses. They are characterized by their β-1,4-glycosidic linked backbone composed of mannose or a combination of mannose and glucose residues. The backbone can be substituted by α-1,6-linked galactose residues. β-mannanases cleave the internal β-1,4-glycosidic bonds

BackgroundDuring bacterial infections of the airways, a Th1-profiled inflammation promotes the production of several host defense proteins and peptides with antibacterial activities including -defensins, ELR-negative CXC chemokines, and the cathelicidin LL-37. These are downregulated by Th2 cytokines of the allergic response. Instead, the eosinophil-recruiting chemokines eotaxin-1/CCL11, eotaxin-2
