  1. 1. Receptor use of primate lentiviruses

    Författare :Dalma Vödrös; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :HIV; SIV; animal models; receptor use; neutralizing antibodies; CD4-independence;

    Sammanfattning : Human and simian immunodeficiency viruses (HIV and SIV) enter target cells using CD4, the primary cell surface receptor and a secondary receptor, called coreceptor. Coreceptor use of HIV can be related to other biological features of the virus and to the severity of infection as well. LÄS MER

  2. 2. Galanin receptor ligands : Design, synthesis, characterization and biological effects

    Författare :Kristin Webling; Ülo Langel; Tore Bengtsson; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : Galanin is a 29/30 amino acid long bioactive peptide discovered over 30 years ago when C-terminally amidated peptides were isolated from porcine intestines. The name galanin originates from a combination of the first and last amino acids - G from glycine and the rest from alanine. LÄS MER

  3. 3. Computational Modeling of the AT2 Receptor and AT2 Receptor Ligands : Investigating Ligand Binding, Structure–Activity Relationships, and Receptor-Bound Models

    Författare :Christian Sköld; Anders Karlén; Anders Hallberg; Torbjörn Lundstedt; Tommy Liljefors; Uppsala universitet; []
    Nyckelord :Pharmaceutical chemistry; Angiotensin II; AT1; AT2; SAR; bioactive conformation; turn mimetic; peptidomimetic; DISCO; homology model; 3D-QSAR; CoMFA; Farmaceutisk kemi;

    Sammanfattning : Rational conversion of biologically active peptides to nonpeptide compounds with retained activity is an appealing approach in drug development. One important objective of the work presented in this thesis was to use computational modeling to aid in such a conversion of the peptide angiotensin II (Ang II, Asp-Arg-Val-Tyr-Ile-His-Pro-Phe).

    Sammanfattning : This thesis work is divided in two parts. In the first part, I make use of the transgenic TRPV1-Cre mouse line as a tool to investigate the midbrain ventral tegmental area (VTA). LÄS MER

  5. 5. Biomarkers in non-small cell lung carcinoma : methodological aspects and influence of gender, histology and smoking habits on estrogen receptor and epidermal growth factor family receptor signalling

    Författare :Christina Karlsson; Karin Piehl-Aulin; Ulf Tidefelt; Gisela Helenius; Leif Johansson; Örebro universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Non-small cell lung carcinoma; estrogen receptor; epidermal growth factor receptor; HER-4; tissue microarray; immunohistochemistry; smoking habits; in situ hybridisation; Onkologi; Oncology;

    Sammanfattning : Non-small cell lung carcinoma is a leading cause of cancer mortality worldwide. There are gender and smoking associated differences both in tumour types and clinical outcome. Squamous cell carcinomas (SCC) are more frequent among smoking men while females develop adenocarcinomas (ADCA). LÄS MER
