9. Dendritic cell development in haematological malignancies and neoplasia

Author

Abstract

Dendritic cells (DC) play a major role in the detection of antigens, initiation of immunity and induction and regulation of tolerance. DCs are Bone Marrow (BM) derived and their development may be influenced by haematological malignancy in several ways. Firstly, myelodysplastic, myeloproliferative or leukaemic transformation of bone marrow progenitors may involve DC precursors directly, when they become part of a malignant clone, or indirectly when neoplastic expansion of other lineages compromises the development of DCs. Secondly, neoplasia of the dendritic cell lineage itself may occur in a heterogeneous group of histiocytic disorders including Langerhans cell histiocytosis (LCH) and Erdheim Chester disease (ECD). The first part of this thesis concerns the effect of haematological malignancies on the generation of DCs; in particular the relationship between DC, monocyte, B and NK lymphoid cell (DCML) deficiency, caused by GATA2 gene mutations, sporadic myelodysplastic syndrome (MDS) and acute myeloid leukaemia (AML). Comprehensive flow cytometric methods for profiling of the DCs and monocytes in the peripheral blood (PB) and peripheral tissues, and the CD34+ progenitors of the BM have been developed. Using these methods, it was possible to see that patients with the three diseases differed on several grounds. DCML deficiencies associated with a younger age of presentation, better preserved haemoglobin, neutrophils and platelets and much more severe defects of DCs, monocytes, and lymphoid cells. In patients with MDS, deficiencies are more moderate and mononuclear cell generation in AML patients is surprisingly preserved. Serum levels of Fms-like tyrosine kinase 3 ligand (FLT3L) also differed, with massively increased levels in DCML deficiency, stable levels in MDS and deficiencies in AML. Finally, strategies of grouping of AML patients have proven to be possible by using progenitor cell or DC related phenotypic markers which may correlate to known cytogenetic abnormalities. The second part of this thesis explores the origin of the cells of LCH and ECD, both neoplasia involving DC-like cells. RT-PCR assays were developed to detect the BRAFV600E mutation, which is present in ~60% of LCH and ECD viii cases. Surprisingly, it was seen that LCH and ECD express BRAFV600E in differing peripheral blood fractions. In LCH, 78-94% of all BRAFV600E alleles were found in HLA-DR+Lineage- cells, localised to the monocytes and CD1c+ myeloid DCs (mDCs). However in ECD, 80-82% of mutated alleles were recovered from the HLA-DR-Lineage- quadrant, localised to CD33+ early myeloid cells, and no mutation was found in the monocytes or mDCs. The final part of the thesis examines whether the circulating cells which carry the BRAFV600E mutation in LCH and ECD can actually develop into LCH-like cells. In order to do this, culture systems were developed with a variety of cytokines and conditions. These experiments showed that CD14+ and CD16+ monocytes and CD1c+ mDCs could all induce the Langerhans Cell (LC) markers CD1a and Langerin in response to GM-CSF, TGFβ and BMP7, however only the CD1c+ mDCs could express Langerin at the high levels seen in LCs, along with EpCam and Birbeck granules. Several techniques have been developed to study DCs in haematological malignancies. Throughout this thesis, these techniques have provided valuable data on the development and homeostasis of human DCs.

18. Polynuclear copper-lanthanoid complexes of pyridone ligands

Abstract

The crystal structures of several copper and mixed copper-lanthanoid complexes are reported, using the 6-chloro and 6-methyl derivatives of 2-pyridone as a ligand. With 6-chloro-2-pyridone, a novel dimeric copper complex results, which has been structually and physically studied. This species, under certain conditions, exhibits a dissociation reaction which has been examined using U.V.-vis. and E.P.R. spectroscopy and by cyclic voltammetry. Reaction of this dimeric copper compound with methanol and ethylene glycol results in the formation of tetranuclear and polymeric copper complexes respectively, which have both been structurally characterised. The reaction of this copper dimer with various lanthanoids results in the formation of a series of mixed copper-lanthanoid species based on four structural types. Reactions in methanol dichloromethane result in three structural configurations depending on size of the lanthanoid used (with La and Ce, LnCu3 with five ligands; with Gd, Dy and Er LnCu3 with eight ligands and for Yb Ln2Cu2 with four ligands). The reaction of lanthanum with the dimeric copper species in a variety of solvents gave a further two structures, one of which (in ethanol) has a similar structure to those observed with Gd, Dy and Er in methanol, while in acetonitrile a fourth structural type occurs, based on La2Cu2 with six ligands. With the 6-methyl-2-pyridone an unusual hexanuclear 'metallocrown' results, which has been characterised structually and by proton and sodium-23 NMR. The reaction of this species with lanthanoids in methanol yields a range of closely related mixed copper-lanthanoid compounds all based on Ln2Cu2 (as seen for the product of Yb with the copper dimer in methanol). The only difference between the structures is a change in the coordination number of the lanthanoid between Sm and Gd to accommodate the contraction in lanthanoid size. The mixed phase reaction of this 'metallocrown' with lanthanum nitrate yields an extremely remarkable structure based on a La8Cu12 core.

The present study aims to explore the inherited genetic component of ECD by performing the first genome-wide association study., [Methods] After quality controls, a cohort of 255 ECD patients and 7,471 healthy donors was included in this study. Afterwards, a logistic regression followed by in silico functional annotation was performed., [Results] A signal at the 18q12.3 genomic region was identified as a new susceptibility locus for ECD (p-value=2.75x10-11; OR=2.09). This association was annotated to the SETBP1 gene, which is involved in clonal haematopoiesis. Functional annotation of this region and of the identified suggestive signals revealed additional genes that could be potentially involved in the pathogenesis of the disease., [Conclusion] Overall, this work demonstrates that germline genetic variants can impact on the development of ECD and suggests new pathways with a potential pathogenic role.

Abstract

A study was conducted on gas-phase diffusion coefficients in unsaturated soils. Steady-state and unsteady-state methods and a new one-flow sorbent-based technique were used at various water contents. Results showed a curvilinear relationship between the effective diffusion coefficient and air-filled porosity. The one-flow sorbent-based technique was found to provide improved characterization of diffusive processes in soils due to its convenience and flexibility.

Abstract

Researchers used empirical packing potential energy measurements, van der Waals volume investigation and computer graphics to study the crystal structures of 28 hexanuclear carbonyl cluster anions, and to study the association between shape, size and charge of the component ions and the development of selective agregates (piles, 'snakes', layers) in the crystal lattice. In the case of large organic cations, the packing type is basically that of molecular mixed crystals, but small cations move toward monodimensional aggregation of the anions.

Abstract

Germinal centers (GCs) are microanatomical structures critical for the development of high-affinity Abs and B cell memory. They are organized into two zones, light and dark, with coordinated roles, controlled by local signaling. The innate lectin-like transcript 1 (LLT1) is known to be expressed on B cells, but its functional role in the GC reaction has not been explored. In this study, we report high expression of LLT1 on GC-associated B cells, early plasmablasts, and GC-derived lymphomas. LLT1 expression was readily induced via BCR, CD40, and CpG stimulation on B cells. Unexpectedly, we found high expression of the LLT1 ligand, CD161, on follicular dendritic cells. Triggering of LLT1 supported B cell activation, CD83 upregulation, and CXCR4 downregulation. Overall, these data suggest that LLT1–CD161 interactions play a novel and important role in B cell maturation within the GC in humans., The Journal of Immunology, 196 (5), ISSN:0022-1767, ISSN:1048-3233, ISSN:1047-7381, ISSN:1550-6606

48. The path to transformation, navigating the barriers to forming the transient and the transitional learning groups in interprofessional education

Author

Gurbutt, Dawne and Milne, Paul

Subjects

Abstract

The creation of a new medical school provided new opportunities to develop interprofessional education (IPE) with a pedagogic basis in transformational learning. The programme involved some transient groups – medical students working with different professional groups throughout the year and some learning interventions which proved to be transitional for students in intended and sometimes unintended ways. The path to transformational learning in interprofessional education requires the navigation of different perspectives and beliefs about learning, an element of tenacity and bravery in relation to holding to core pedagogic beliefs and an openness to co-production and evolution of learning elements. \ud Some learning episodes formed a transformative space within a particular time bounded location whilst others led to ongoing relationships and social connections beyond the classroom. Feedback indicated that transformation is not always comfortable or linear for students and the programme identified areas of challenge for both learners and staff as well as opportunities for development and co-creation. \ud This was a large IPE initiative involving staff and students from 9 disciplines across 7 schools and 3 faculties with involvement from service users and stakeholders. The programme incorporated almost 2000 separate student learning episodes. This paper will consider the programme from the perspective of students, creators of the learning elements and participatory staff from different disciplines, exploring the challenges, gains and learning from the initiative. \ud In considering these we suggest that social learning paradigms can help to give insight into their solution. For example, the intended and unintended outcomes could be considered through the perspectives of an integrated social learning paradigm. From the empirical data it is suggested that the paradigms of Activity theory and Complex adaptive systems theory give insight to how intended and unintended transformative learning takes place. These are inter-related as shown in the diagram.\ud Using complex adaptive system theory as part of the activity system theory paradigm, the inter-relationship between the components of the suggested social learning paradigm may be viewed as complex with any one component able to take precedent over the other. \ud It is suggested that the unintended transformative learning and the social connections established outside the classroom arose as a result of the mixed student professionals’ classroom moving through a process of having become a ‘self-organising system’. The students have spontaneously produced a system that could not have been predicted from ‘a knowledge of the previous state’ (i.e. the facilitated teaching session).\ud Analysis of the empirical data through the lens of social learning theories gives insight into the ‘how and why’ transformative learning takes place and might help to plan IPE sessions with greater confidence.
