Research group - Anders Sönnerborg (Labmed)
Translational research on HIV and other chronic infections.
Our research group consists of four major research teams from Division of Clinical Microbiology, Department of Laboratory Medicine and Division of Infectious Diseases, Department of Medicine Huddinge. The researchers interact closely and integrate experimental, translational and clinical research with focus of solving key problems related to HIV treatment, HIV cure, long-term consequences and the spread of HIV.
The driving question of the Microbiota-inflammation team, headed by Dr Piotr Nowak, MD, PhD, is the role of the microbiome in chronic infections like HIV/HCV and Mycobacterium tuberculosis. Also the mechanisms behind success of microbiome modulation in the clinic are investigated.
The Antiviral team performs clinical research on antiretroviral therapy including academic and industry-sponsored in vivo studies. It is also involved in cohort studies of ART in low-middle income countries. The experimental antiviral research is focused on HIV drug resistance, methods for quantification and elimination of latent HIV and the antiretroviral sensitivity of different subtypes.
Team Register studies is headed by Associate Professor Veronica Svedhem, MD, PhD whose research is based on data from the national InfCareHIV database, covering all Swedish patients. These cohort studies are focused on evaluating new treatment outcomes, long-term side effects, non-HIV related morbidity and life quality over time. InfCareHIV is then connected to other national databases like Statistics Sweden, Cause of Death and Cancer Registers.
Team HIV epidemiology and Molecular phylogenetics, headed by Dr Johanna Brännström, MD, PhD is divided into a clinical oriented unit with focus on the undiagnosed population, late testers and HIV continuum of care and an experimental unit with focus on molecular epidemiology, phylogenetics and phylogeography. The two units interact extensively.

Techniques and infrastructure
Techniques
- High throughput sequencing; Transcriptomics; Proteomics; Metabolomics; RNAscope; Microfludics; miRNA profiling; Integrated system biology; Cell cultures; Large databases; Real-time PCR
Infrastructure
- The clinical HIV unit is fully equipped for phase IIa-IV studies fulfilling GCP criteria. It has also a biobank of 4 freezers (-20ºC, -70ºC), computers, servers, access to IT-infrastructure of the hospital. Infrastructure at the HIV unit includes clinical examination rooms, dressing room, library etc. For all patients there are clinical electronic patient records. Selected clinical and laboratory data are once a night automatically transferred to the research InfCare HIV database.
- Laboratory at Division of Clinical Microbiology consists of four physically separated biosafety level 2 rooms handing of infectious materials and dedicated four room PCR- set up (sample preparation, reagent preparation, template and post PCR gel documentation) with unidirectional movement. The main lab also has bench spaces as well as separate space for laboratory equipments and chemical storage. Standard equipment is available in the laboratory including six -20ºC freezers dedicated for each room for storage of reagents and samples, ten minus 80°C freezers dedicated for long term storages of samples. The lab also has four BSL Class2A biosafety cabinets and two PCR stations for reagent preparation and template mixing. There is a refrigerated centrifuge with swing out rotor (Eppendorf 5810R), refrigerated Microcentrifuge 5417R (Eppendorf) and a MiniSpin (Eppendorf). The lab also has five thermal cyclers (gradient and non-gradient) and NanoDrop to quantitate nucleic acids/proteins. Lab has two gel documentation system (GeneGenom and Genei) and six electrophoresis units with power packs. The laboratory also have two mono-chromator based ELISA reader of wavelength range 340-850 nm (Techcan) and automated plate washer. The lab as access to one BSL Class3 laboratory.
- Specialized equipment’s like flow cytometers, Applied Biosystems® 7500 Real-Time PCR Systems, VictorX3 Luminometer, CASY cell counter, Agilent 2100 platform, fluorscent microscope unit, PCR set-up as per GLP recommendation (separate Pre-Amplification, Amplification and Post-Amplification areas) liquid scintillation counters, inverted phase contrast microscopes with fluorescence, automated ELISpot reader, PCR thermal cyclers, double distillation unit, Gel doc systems, ELISA Reader (3).
- Laboratory has access to the Illumina HiSeq 2500 and MiSeq through centralized facilities and access to the for long-term storage of data sets to store data in a high-availability and high-security system based on iRODS through BILS (Bioinformatics Infrastructure for Life Sciences) is a distributed national research infrastructure supported by the Swedish Research Council (Vetenskapsrådet). The storage system automatically replicates data sets to two different data centers, and there is fine-grained access-control to share data to specific users.
- Apart from that research group has access to Karolinska Institutet Core Facilities for proteomics, genomics and imaging required for the study, that is an umbrella definition for service laboratories, resources and competence centres whose activities are coordinated, supervised and partly financed by the Board of Research (FS) in collaboration with the local committees for Research and Education (FoUU) of the associated hospitals.
- A top modern laboratory is presently built at Alfred Nobels Alle, Campus Flemingsberg, Huddinge, KI. The research group has already moved into the new offices. The lab.space will be inaugurated in Autumn 2018. The equipment will be top modern and the decision process is presently ongoing.
