Subprojects
The subprojects of the CRC1066 consist of the projects of subareas A and B as well as the cross-sectional projects (Q) and the central projects (Z).
Subarea A
In subarea A, very different carriers are provided from the chemical side, taking into account both complex covalently linked polymer architectures and self-assembling structures.
This project combines the use of carbohydrates, both as structural material for the preparation of nanoparticles and nanocapsules and as targeting moieties to achieve selective binding to certain immune cells. By working with polysaccharide based nanocapsules with high loading efficiencies it aims to prepare stimulus responsive carriers, which bind selectively to certain subpopulations of immune cells to release their cargo.

This project aims to control morphology and function of brush-like peptidic carriers, which are either derived from living polymerization or result from (further processed) natural monodisperse peptides. In addition, peptide based targeting units are modified to allow selective ligation. In combination this project aims at the preparation of systems to study, how morphology (rod or sphere like structures) and/or the ligation of antibodies modify the interaction of the carriers with immune cells.

Within this project the processing and loading (formulation) of polymersomes and liposomes as car-riers for peptides, RNA and/or low molar mass pharmacons will be studied. It is thereby the speciality of these polymersomes that they can be coated with hyperbranched PEG and decorated with targeting structures. To modify the release as recondition for biomedical activity the stability of the basic polymersomal structure will be modified to allow stabilization (e.g. crosslinking) or destabiliza-tion by pH dependent degradation.

Subarea Q
The cross-sectional projects (Q) form the natural bridge between the A and B projects. They are of central importance for the majority of the subprojects in the A and B areas and are characterized by a very high CRC-specific research content.
The goal of TP Q1 is to analyze interactions between nanocarriers and blood components. Molecular determinants will be analyzed that lead to enhanced in vivo uptake and improved efficacy of the intended immunomodulation induced by polymer- and lipid- based NP developed within the CRC1066, with a focus on the protein corona, protein-lipid interactions, and the role of lipids in general. This is done by physico-chemical characterization methods, molecular simulations, and data-driven modelling. The protein corona is analyzed by dynamic light scattering, mass spectrometry, microcalorimetry, and a recently established AF-FFF-based separation technique.

Q2 will focus on the characterization of the nanocarriers (NC) and their interactions with biological matter. Ex vivo fluorescence correlation spectroscopy will study the NC kinetics in the blood of living animals with respect to possible aggregation, degradation or premature release of cargo. Furthermore, the structure of the NCs protein corona and its influence on endocytosis processes will be reconstructed by 3D cryo electron microscopy. The type and effectiveness of intracellular drug release from NCs, as well as the effective-ness of major histocompatibility complex (MHC) loading and stimulation of T cells, will be analyzed by proteomics of intracellular compartments and by transcriptome analysis using RNASeq. ex-vivo-Fluorezenz-Korrelationsspektroskopie wird die NC-Kinetik im Blut lebender Tiere bezüglich Aggregation, Degradation oder vorzeitiger Wirkstoff-Freisetzung untersuchen.

This project aims at in vivo imaging of the biodistribution of nanodimensional carriers on different length scales (from organ to cellular assembly) by PET- and optical methods. It is thereby the inten-tion to validate fluorescence imaging against the quantitative PET method. In addition, methods to visualize the activation of the immune system (immuno-imaging) as result of the immunotherapy will be developed.

In TP Q4, human-relevant animal models and in vitro systems as alternatives to animal models, which are of use for the entire SFB, will be further developed and characterized by investigating the genetic variability and neoantigen expression in spontaneously developing murine melanomas and by establishing methods for standardized procedures of immunotherapy experiments in spontaneous tumor models. Furthermore, animal model alternatives, such as tumor organoids will further be improved to analyse changes in the tumor microenvironment and to investigate the effects of NP on the tumor-specific immune response.

The new project Q5 will further evolve the existing nanocarrier systems within the CRC through new chemical ligation methods and selective targeting structures. For an effective targeting of immune cells, e.g. saccharidic recognition sequences (oligosaccharides) will be attached to the nanocarriers through responsive linker systems. As a practical application of newly developed targeting structures and their conjugation chemistry, inhibitors of the cysteine-cathepsin S, an important regulator of antigen presentation, will be conjugated to nanoparticles or used as a non-covalent payload. The resulting constructs will be evaluated as potential tumor therapeutics.

The work of TP Q6 will focus on the analysis of protein corona and the biodistribution of nanomaterials after systemic application. Extending the work of previous TP B11 and TP A7, the composition and relevance of the protein corona for blood circulation and the targeting of NP will be analyzed. In particular, the importance of different antibody formats (whole antibody, Fab fragments, scFv, nanobodies) and their suitability for targeting efficiency will be further explored. Furthermore, the effects of different surface modifications (chemical variation of polyether architectures and functionality) on protein corona and in vivo targeting by surface functionalization (Fab antibody fragments, nanobodies) will be investigated.

Subarea B
Subarea B groups together the projects that are primarily concerned with the application of nanoparticles and polymers for tumor immunotherapy.
M2-type cancer promoting macrophages in the liver cancer microenvironment will be repolarized to cancer suppressing M1-type macrophages using block copolymer-based cationic nanogels. The nanoparticles will be loaded with small molecular drugs, siRNA or antisense oligonucleotides. Targeted delivery and thus a more effective repolarization of M2-macrophages will be further improved by derivatisation of the nanoparticles with CD206-binding peptides or nanobodies. For in vivo efficacy testing we have established 3 syngenic mouse models of hepatocellular carcinoma. in vivo Effektivitätstestungen wurden 3 syngene Mausmodelle des hepatozellulären Karzinoms etabliert.

Multifunctional nanoparticles equipped with tumor antigens and immunostimulatory TLR-agonists, as well as targeting units for addressing antigen-presenting cells (APC), can trigger an effective immune response against established murine tumors after systemic application. For this purpose, this subproject will establish biodegradable, poly(carbonate-)-based nanogels and characterize their immunotherapeutic efficacy in injected, metastatic and inducible melanoma models. Beyond the relevance of different APC populations and immune effector cells, the role of B-cells for tumor vaccine responses will be deciphered in detail.

This project will develop DNA-vaccines, which are under the translational control of the Fascin-promotor and thus only active in dendritic cells. Since dendritic cells as – non-dividing cells – are rather difficult to transfect, the expertise of E. Wagner and R. Zentel will be combined to develop new, more efficient stimulus responsive transfection systems from blockcopolymers and cationic oligomers.

STAT3-mediated tumor-associated processes will be modulated by use of STAT3 inhibitor loaded functionalized nanocapsules. We will analyse the impact on tolerogenic DC and myeloid cells and, in particular, on T cells (regulatory FOXP3+, cytotoxic CD8+ T cells), thereby taking advantage of the established method of IL-2 functionalized nanocapsules for T cell targeting. Further studies will unravel the therapeutical effect of our nanocapsule-based systems (+/- immunotherapies) in murine and humanized [MISTRG] models of malignant melanoma in vivo. in vivo getestet und mit weiteren Immuntherapien kombiniert.

We have shown that adenylyl cyclase inhibitor-loaded polypept(o)ide micelles suppress the growth of melanomas by repressing intratumoral cAMP formation. In preparation of a clinical trial, the effect of particle-mediated cAMP repression on human melanomas and syngeneic human immune cells will now be investigated in the humanized MISTRG mouse melanoma model. We aim to to make micelle-mediated cAMP repression by adjuvant nanoparticles even more effective and to identify the involved signal transduction pathways in tumor-infiltrating leukocytes by comparative transcriptome analyses.

Starting with the observation that some nanocarriers build up a protein corona nearly instantaneously in context with serum proteins, which has serious results for cellular uptake and intra-cellular trafficking, this project aims at three different topics. At first it will study possible corona formation on more carrier systems to determine the generality of this phenomenon. Then the applicants want to look for ways to pre-organize desired proteins in the corona to modify biodistribution. At last it is the aim to bind desired proteins like clusterin and/or antibodies chemically to obtain –in this way- a stealth like behavior.

Aim of TP B12 is the development of medically applicable nanoparticular delivery systems to allow functional modulation of T- and NK-cells by mRNA-coding cytokines. RNA-Lipoplex-NP initially developed by Sahin et al. are already investigated in clinical studies for the treatment of melanoma. To further expand the concept of mRNA based immune therapies onto T- and NK-cells polymer-lipid-hybrid and ligand systems were established and will be further developed regarding their clinical translation for immune therapies of melanoma.

TP B13 established a modular vaccine platform using molecular (glyco)peptide building blocks. These carry tumor-associated antigens or immuno-stimulatory components and co-assemble into anisotropic multifunctional nanorods. The platform was successfully applied as fully synthetic vaccines against tumor-associated Mucin 1 during the previous funding period and will now be used to develop vaccines against malignant melanoma. Synthetic B-cell epitopes derived from melanoma associated surface protein CSPG4 will be co-presented on the nanorod surface, with T-cell epitopes and immunomodulating agents, and will be evaluated in vivo in terms of tumor-specific antibody induction and therapeutic effect.

In a humanized mouse model of malignant melanoma, immunomodulation in tumor tissue is addressed, in particular by targeting inhibitory cell populations. pH-responsive liposomes from the previous funding period are further developed into smart, programmable liposomes with time-programmable release and pH-modulating properties in order to selectively release active substances combined with pH-modulation of the tumor microenvironment for intervention in the signaling pathways of mainly macrophages, regulatory T cells (Treg) and tumor cells.

Nanovaccines accumulate in the liver typically in tolerance-promoting KC (Kupffer cells) and LSEC (sinusoidal liver endothelial cells). Both cell types can be reprogrammed to serve as antigen presenting cells by applying suitable adjuvants. B15N develops nanovaccines which besides dendritic cells also address and activate KC/LSEC. This approach serves to induce potent anti-tumor responses in liver and skin (metastatic melanoma). The suitability of protein nanocapsules containing peptid antigen/adjuvant and of liposomes loaded with antigen-coding mRNA/nucleic acid-based adjuvants to serve as nanovaccines will be evaluated.

The goal of B16N is to change the metabolic status of the tumor microenvironment using pH-modulating nanocarriers. Aggressive, fast-growing tumors are characterized by an acidic microenvironment that pro-motes the differentiation of a non-inflammatory macrophage subtype. The increase of the pH value will be imaged using PET and the resulting effects on tumor infiltrating immune cells will be investigated using PET and OMICS analyses. Furthermore, tumor spheroids generated from human tumor biopsies are used to translate pH modulation and its effects on immune cell infiltrates to human tumors.

Nanoparticles are decorated with CAF-targeting ligands, loaded with CAF-modulating drugs (e.g. anti-TGFβ1 siRNA, AT1R-antagonists) and tested in vitro (in i.a. tumor organoids) to select promising candidates for therapeutic in vivo experiments. After biodistribution and tumor tissue accumulation of the drug-loaded nanoparticles have been assessed by multimodal imaging methods, therapeutic antitumor effects of the validated drug-loaded nanoparticles are studied in relevant murine liver tumor models, whereby i.a. RNA- and proteomics are applied to gain insight into therapeutic mechanisms.
