1. 1. Mechanisms for immune escape in epithelial ovarian cancer

   Författare :Pernilla Israelsson; Ulrika Ottander; Lucia Mincheva-Nilsson; Eva Lundin; Ivan Nagaev; Karin Sundfeldt; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human; ovarian cancer; high-grade serous cancer; EOC; HGSC; HGSOC; tumor microenvironment; immune escape; immune suppression; cytokines; exosomes; NKG2D; MICA B; ULBP1-3; DNAM-1; surgery; obstetrik och gynekologi; Obstetrics and Gynaecology;

   Sammanfattning : Tumors develop mechanisms to subvert the immune system, constituting immune escape. Epithelial ovarian cancer (EOC), the deadliest of all gynecological malignancies, uses a variety of mechanisms to undermine immune surveillance, aiding its establishment and metastatic spreading.

3. 2. Immune modulation in serous epithelial ovarian cancer : focus on the role of tumor-derived exosomes

   Författare :Alireza Labani Motlagh; Lucia Mincheva-Nilsson; Ola Winqvist; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ovarian cancer; EOC; HGSC; exosomes; NKG2D; MICA B; ULBP; DNAM-1; PVR; nectin-2; lncRNAs; immune suppression; anti-tumor immunity; NK-cell cytotoxicity; cytokines; Th1; Th2; T regulatory response; inflammation; tumor microenvironment;

   Sammanfattning : Serous epithelial ovarian cancer (EOC) is a potent suppressor of the immune defense. Here, we studied interactions between EOC and the immune system that lead to escape from tumor immune surveillance. LÄS MER

5. 4. Receptor tyrosine kinase signaling and extracellular matrix cues in ovarian cancer metastasis and drug resistance

   Författare :Lidia Moyano Galceran; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Albeit many studies have contributed towards understanding the origin, development, treatment response and evolution of high-grade serous ovarian carcinoma (HGSC), the exact supporting mechanisms are still not fully understood, and the disease remains a clinical challenge with low 5-year survival and high recurrence rate. The purpose of this thesis was to study the dynamic communication between the cancer cells and the tumor microenvironment (TME) to understand how these influence and are affected by disease progression and chemotherapy in the context of HGSC.

7. 5. Modeling and investigations of high-grade glioma to understand tumorigenesis and heterogeneity

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glioblastoma; diffuse pediatric-type high-grade glioma; cell of origin; heterogeneity; serum culture; glioblastoma stem cell; chromatin accessibility; cross-species conservation; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

   Sammanfattning : Glioblastoma (GBM) is the most common primary malignant brain tumor. As per 2021 WHO classification, the corresponding diagnosis in children is called diffuse pediatric-type high-grade glioma (pHGG). In both cases tumors are histone 3 (H3) and isocitrate dehydrogenase 1/2 (IDH1/2) wildtype (wt). LÄS MER
