Said ASCII copy, created on August 3 , 2017, is named PAT057169-WO-PCT_SL.txt and is 146,992 bytes in size. FIELD [003] The present disclosure is in the field of immunology. In particular, this disclosure is directed to methods of immunization using compositions comprising cationic lipids and polynucleotide molecules, such as polyribonucleotide molecules, e.g., mRNA, which code for immunogens (e.g., a target protein or a fragment thereof). This disclosure is also directed to methods for producing antibodies (e.g., monoclonal antibodies) from immunized animals (e.g., non-human animals) for the purposes of making therapeutic antibodies, as well as to the antibodies themselves. BACKGROUND [004] Therapeutic monoclonal antibody development in vivo is often limited by the ability to produce a high quality antigen that can be used for immunization. Ideally, the antigen should be a highly purified protein with an intact structural conformation and have enough sequence variation from the animal host strain as to break immunological tolerance and induce a robust humoral response. For many target proteins intended for use as antigens, however, meeting these requirements is not possible due to such issues as inherently poor biophysical properties of the protein that proscribe overexpression/purification, cytotoxicity in host production cells, and poor immunogenicity of the target protein's amino acid sequence. [005] Traditional methods of animal immunization have employed two general strategies for the generation of antibodies. The first involves repeated injections of full length protein antigen in purified format in the presence of an adjuvant to enhance the immune response. For small to medium-sized soluble proteins, this procedure can be a successful method for the generation of monoclonal antibodies against an antigen in its native conformation. For very large proteins, l transmembrane proteins, proteins with unusual post translational modifications, or proteins with poor solubility, this method is of very limited utility, as obtaining pure native, full length protein in the quantities needed for immunization is difficult. The second strategy entails immunization of animals with a DNA construct which encodes the antigen of interest. This strategy allows for the expression of difficult to purify proteins in their native state in situ. It suffers, however, from a relatively low antibody titer generation, which can ultimately correlate with a low yield of monoclonal hybridoma production (Howard et al. Making and using antibodies: A Practical Handbook, 2nd Edition CRC Press, 2013). SUMMARY [006] The present disclosure is directed to a method for eliciting an immune response in an animal (e.g., non-human animal), comprising the steps of: (a) mixing at least one cationic lipid with a polynucleotide, such as polyribonucleotide (e.g., mRNA), coding for an antigenic determinant, thereby forming a cationic lipid-polynucleotide complex; and (b) administering the lipid-polynucleotide complex to the animal. The present disclosure is further directed to a genetic immunization method wherein the polynucleotide is a polyribonucleotide molecule such as an mRNA molecule which codes for an immunogen (e.g., a target protein or a fragment thereof). The present disclosure is further directed to a method for producing antibodies (e.g., polyclonal or monoclonal antibodies) comprising the use of genetic immunization method described herein, and further comprising the step of isolating the antibodies from the immunized animal. [007] The present disclosure is also directed to a method for producing monoclonal antibodies comprising the steps of: (a) mixing at least one cationic lipid with a polynucleotide, thereby forming a lipid-polynucleotide complex, wherein the polynucleotide comprises an mRNA sequence coding for an immunogen; (b) administering the lipid-polynucleotide complex to at least one mouse; (c) removing antibody-producing cells such as lymphocytes (e.g., B-lymphocytes) or splenocytes from the immunized mice; (d) fusing the B-lymphocytes from the immunized mice with myeloma cells, thereby producing hybridomas; (e) cloning the hybridomas; (f) selecting positive clones which produce anti-immunogen antibody; (g) culturing the anti-immunogen antibody-producing clones; and (h) isolating anti-immunogen antibodies from the cultures. In certain aspects, the methods provided herein for producing antibodies comprise further steps to determine the amino acid sequence of the heavy chain variable region and light chain variable region of such antibodies as well as the corresponding encoding nucleic acid sequences. In particular aspects, the methods provided herein for producing antibodies comprise further steps to generate a chimeric antibody or humanized antibody of the anti-immunogen antibody. [008] The present disclosure is also directed to a method in which immune tissues are collected from animals immunized with mRNA containing cationic lipid nanoparticles (LNPs) and B cells are selectively isolated. The B cells are directly screened for the production of an antibody with the desired properties and the antibody is directly cloned and expressed recombinantly, bypassing the need for generation of hybridomas. [009] The mRNA encapsulated LNPs of the present disclosure may also be used for the purpose of generating a recombinant antibody library from the immune tissues of an immunized host animal (e.g., rodents (e.g., mice and rats), rabbits, chickens, cows, camelids, pigs, sheep, goats, sharks, and non-human primates, etc.). This library can then be subsequently screened in a heterologous host system, such as phage or yeast display for the desired properties. [0010] The methods of polynucleotide-based, e.g., mRNA-based, immunization of the present disclosure have addressed many of the issues associated with the above-described difficulties inherent in antigen production and/or antibody generation. Among other things, said methods dispense with the need to directly express and purify the target protein antigen.

  • Investigation of the Fatty Acid Transporter-Encoding Genes
    www.nature.com/scientificreports OPEN Investigation of the fatty acid transporter-encoding genes SLC27A3 and SLC27A4 in autism Received: 13 February 2015 1 1 1 1 Accepted: 12 October 2015 Motoko Maekawa , Yoshimi Iwayama , Tetsuo Ohnishi , Manabu Toyoshima , 1 1 1 1 2,3 Published: 09 November 2015 Chie Shimamoto , Yasuko Hisano , Tomoko Toyota , Shabeesh Balan , Hideo Matsuzaki , Yasuhide Iwata3, Shu Takagai3, Kohei Yamada3, Motonori Ota4, Satoshi Fukuchi5, Yohei Okada6,7, Wado Akamatsu6,8, Masatsugu Tsujii3,9, Nobuhiko Kojima10, Yuji Owada11, Hideyuki Okano6, Norio Mori3 & Takeo Yoshikawa1 The solute carrier 27A (SLC27A) gene family encodes fatty acid transport proteins (FATPs) and includes 6 members. During fetal and postnatal periods of development, the growing brain requires a reliable supply of fatty acids. Because autism spectrum disorders (ASD) are now recognized as disorders caused by impaired early brain development, it is possible that functional abnormalities of SLC27A genes may contribute to the pathogenesis of ASD. Here, we confirmed the expression of SLC27A3 and SLC27A4 in human neural stem cells derived from human induced pluripotent stem cells, which suggested their involvement in the developmental stage of the central nervous system. Additionally, we resequenced the SLC27A3 and SLC27A4 genes using 267 ASD patient and 1140 control samples and detected 47 (44 novel and 29 nonsynonymous) and 30 (17 novel and 14 nonsynonymous) variants for the SLC27A3 and SLC27A4, respectively, revealing that they are highly polymorphic with multiple rare variants. The SLC27A4 Ser209 allele was more frequently represented in ASD samples. Furthermore, we showed that a SLC27A4 Ser209 mutant resulted in significantly higher fluorescently-labeled fatty acid uptake into bEnd3 cells, a mouse brain capillary-derived endothelial cell line, compared with SLC27A4 Gly209, suggesting that the functional change may contribute to ASD pathophysiology.

  • Slc1a3-2A-Creert2 Mice Reveal Unique Features of Bergmann Glia and Augment a Growing Collection of Cre Drivers and Effectors In
    www.nature.com/scientificreports OPEN Slc1a3‑2A‑CreERT2 mice reveal unique features of Bergmann glia and augment a growing collection of Cre drivers and efectors in the 129S4 genetic background Lech Kaczmarczyk1,2, Nicole Reichenbach2, Nelli Blank2, Maria Jonson1, Lars Dittrich2, Gabor C. Petzold2,3 & Walker S. Jackson1,2* Genetic variation is a primary determinant of phenotypic diversity. In laboratory mice, genetic variation can be a serious experimental confounder, and thus minimized through inbreeding. However, generalizations of results obtained with inbred strains must be made with caution, especially when working with complex phenotypes and disease models. Here we compared behavioral characteristics of C57Bl/6—the strain most widely used in biomedical research—with those of 129S4. In contrast to 129S4, C57Bl/6 demonstrated high within‑strain and intra‑litter behavioral hyperactivity. Although high consistency would be advantageous, the majority of disease models and transgenic tools are in C57Bl/6. We recently established six Cre driver lines and two Cre efector lines in 129S4. To augment this collection, we genetically engineered a Cre line to study astrocytes in 129S4. It was validated with two Cre efector lines: calcium indicator gCaMP5g‑tdTomato and RiboTag—a tool widely used to study cell type‑specifc translatomes. These reporters are in diferent genomic loci, and in both the Cre was functional and astrocyte‑specifc. We found that calcium signals lasted longer and had a higher amplitude in cortical compared to hippocampal astrocytes, genes linked to a single neurodegenerative disease have highly divergent expression patterns, and that ribosome proteins are non‑uniformly expressed across brain regions and cell types.

Abstract: G-protein-coupled receptors (GPCRs) comprise a large protein superfamily divided into six classes, rhodopsin-like (A), secretin receptor family (B), metabotropic glutamate (C), fungal mating pheromone receptors (D), cyclic AMP receptors (E) and frizzled (F). Until recently, GPCRs signaling was thought to emanate exclusively from the plasma membrane as a response to extracellular stimuli but several studies have challenged this view demonstrating that GPCRs can be present in intracellular localizations, including in the nuclei. A renewed interest in GPCR receptors’ superfamily emerged and intensive research occurred over recent decades, particularly regarding class A GPCRs, but some class B and C have also been explored. Nuclear GPCRs proved to be functional and capable of triggering identical and/or distinct signaling pathways associated with their counterparts on the cell surface bringing new insights into the relevance of nuclear GPCRs and highlighting the Citation: Gonçalves-Monteiro, S.; nucleus as an autonomous signaling organelle (triggered by GPCRs).

    Familial Cortical Myoclonus Caused by Mutation in NOL3 by Jonathan Foster Rnsseil DISSERTATION Submitted in partial satisfaction of the requirements for the degree of DOCTOR OF PHILOSOPHY in Biomedical Sciences in the Copyright 2013 by Jonathan Foster Russell ii I dedicate this dissertation to Mom and Dad, for their adamantine love and support iii No man has earned the right to intellectual ambition until he has learned to lay his course by a star which he has never seen—to dig by the divining rod for springs which he may never reach. In saying this, I point to that which will make your study heroic. For I say to you in all sadness of conviction, that to think great thoughts you must be heroes as well as idealists. Only when you have worked alone – when you have felt around you a black gulf of solitude more isolating than that which surrounds the dying man, and in hope and in despair have trusted to your own unshaken will – then only will you have achieved. Thus only can you gain the secret isolated joy of the thinker, who knows that, a hundred years after he is dead and forgotten, men who never heard of him will be moving to the measure of his thought—the subtile rapture of a postponed power, which the world knows not because it has no external trappings, but which to his prophetic vision is more real than that which commands an army. -Oliver Wendell Holmes, Jr. iv ACKNOWLEDGMENTS I am humbled by the efforts of many, many others who were essential for this work.
