  • Contribution of non-genetic factors to dopamine and serotonin receptor availability in the adult human brain
  • 2016
  • Ingår i: Molecular Psychiatry. - London, United Kingdom : Nature Publishing Group. - 1359-4184 .- 1476-5578. ; 51, s. 879-879

    • The dopamine (DA) and serotonin (5-HT) neurotransmission systems are of fundamental importance for normal brain function and serve as targets for treatment of major neuropsychiatric disorders. Despite central interest for these neurotransmission systems in psychiatry research, little is known about the regulation of receptor and transporter density levels. This lack of knowledge obscures interpretation of differences in protein availability reported in psychiatric patients. In this study, we used positron emission tomography (PET) in a twin design to estimate the relative contribution of genetic and environmental factors, respectively, on dopaminergic and serotonergic markers in the living human brain. Eleven monozygotic and 10 dizygotic healthy male twin pairs were examined with PET and [(11)C]raclopride binding to the D2- and D3-dopamine receptor and [(11)C]WAY100635 binding to the serotonin 5-HT1A receptor. Heritability, shared environmental effects and individual-specific non-shared effects were estimated for regional D2/3 and 5-HT1A receptor availability in projection areas. We found a major contribution of genetic factors (0.67) on individual variability in striatal D2/3 receptor binding and a major contribution of environmental factors (pairwise shared and unique individual; 0.70-0.75) on neocortical 5-HT1A receptor binding. Our findings indicate that individual variation in neuroreceptor availability in the adult brain is the end point of a nature-nurture interplay, and call for increased efforts to identify not only the genetic but also the environmental factors that influence neurotransmission in health and disease.

  • Disseqt-distribution-based modeling of sequence space time dynamics
  • 2019

  • Tidskriftsartikel (refereegranskat)abstract
    • Rapidly evolving microbes are a challenge to model because of the volatile, complex, and dynamic nature of their populations. We developed the DISSEQT pipeline (DIStribution-based SEQuence space Time dynamics) for analyzing, visualizing, and predicting the evolution of heterogeneous biological populations in multidimensional genetic space, suited for population-based modeling of deep sequencing and high-throughput data. The pipeline is openly available on GitHub (https://github.com/rasmushenningsson/DISSEQT.jl, accessed 23 June 2019) and Synapse (https://www.synapse.org/#!Synapse: syn11425758, accessed 23 June 2019), covering the entire workflow from read alignment to visualization of results. Our pipeline is centered around robust dimension and model reduction algorithms for analysis of genotypic data with additional capabilities for including phenotypic features to explore dynamic genotype-phenotype maps. We illustrate its utility and capacity with examples from evolving RNA virus populations, which present one of the highest degrees of genetic heterogeneity within a given population found in nature. Using our pipeline, we empirically reconstruct the evolutionary trajectories of evolving populations in sequence space and genotype-phenotype fitness landscapes. We show that while sequence space is vastly multidimensional, the relevant genetic space of evolving microbial populations is of intrinsically low dimension. In addition, evolutionary trajectories of these populations can be faithfully monitored to identify the key minority genotypes contributing most to evolution. Finally, we show that empirical fitness landscapes, when reconstructed to include minority variants, can predict phenotype from genotype with high accuracy.

  • Mean GOSLON Yardstick Scores After 3 Different Treatment Protocols-A Long-term Study of Patients With Unilateral Cleft Lip and Palate
  • 2019
  • Ingår i: The Cleft palate-craniofacial journal : official publication of the American Cleft Palate-Craniofacial Association. - : SAGE Publications. - 1545-1569. ; 56:2, s. 236-247

    • (1) To evaluate dental arch relationships, with the Great Ormond Street, London and Oslo (GOSLON) Yardstick, of participants with Unilateral cleft lip and palate (UCLP) and treated with 1-stage palatal closure with 3 different surgical protocols (2) to compare the mean GOSLON ratings with other CLP centers. Design: Retrospective study of medical charts and dental models. Setting: Karolinska University Hospital, Stockholm, Sweden. Participants: Eighty-seven patients with UCLP operated with 1-stage palatal repair. Thirty-five were operated with Veau-Wardill-Kilner (VWK) technique 1975 to 1986, 31 with minimal incision technique (MIT) from 1987 to 1997, and 21 according to MIT with muscle reconstruction (MITmr) 1998 to 2004. Interventions: Dental casts at ages 5 (n = 87), 7 to 8 (n = 27), 10 (n = 81), 16 (n = 61), and 19 (n = 35) years were rated by 10 assessors with the GOSLON Yardstick. Information of other interventions was retrieved from patients’ charts. Main outcome measures: Mean GOSLON ratings. Results: A total of 82% of the participants were rated as having excellent to satisfactory outcome. Weighted κ statistics for the 10 assessors was good for inter-rater agreement and good/very good for intra-rater agreement. Conclusions: The mean GOSLON score in the Stockholm overall material at age 10 was 2.67. The VWK technique resulted in a greater need of orthognathic surgery than the MIT ( P < .01). The MITmr did not produce better dental arch relationships than MIT at age 5 ( P < .05). The best dental arch relationships were found in the MIT group at 10 years, mean 2.58, which is not significantly different from other centers with excellent outcome except Gothenburg and Vienna.

  • Increasing clinical severity during a dengue virus type 3 Cuban epidemic: deep sequencing of evolving viral populations
  • 2016
  • Ingår i: Journal of Virology. - 1098-5514. ; 90:19, s. 4320-4333
  • Tidskriftsartikel (refereegranskat)abstract
    • During the DENV-3 epidemic occurred in Havana in 2001-2002, severe disease was associated with the infection sequence DENV-1/DENV-3, whilst the sequence DENV-2/DENV-3 was associated with mild/asymptomatic infections. To determine the role of the virus in the increasing severity demonstrated during the epidemic serum samples collected at different point times were studied. A total of 22 full-length sequences were obtained using a deep sequencing approach. Bayesian phylogenetic analysis of consensus sequences revealed that two DENV-3 lineages were circulating in Havana at that time, both grouped within genotype III. The predominant lineage is closely related to Peruvian and Ecuadorian strains, whilst the minor lineage is related to Venezuelan strains. According to consensus sequences, relatively few non-synonymous mutations were observed; only one was fixed during the epidemic at position 4380 in the NS2B gene. Intra-host genetic analysis indicated that a significant minor population was selected and became predominant towards the end of the epidemic. In conclusion, greater variability was detected during the epidemic's progression in terms of significant minority variants, particularly in the non-structural genes. An increasing trend of genetic diversity towards the end of the epidemic was only observed for synonymous variant allele rates, with higher variability in secondary cases. Remarkably, significant intra-host genetic variation was demonstrated within the same patient during the course of secondary infection DENV-1/DENV-3, including changes in the structural proteins PrM and E. Therefore, the dynamic of evolving viral populations in the context of heterotypic antibodies could be related to the increasing clinical severity observed during the epidemic.
