Nucleic acid molecules comprising a nucleotide sequence encoding an activating chimeric antigen receptor (aCARs) are provided, said aCARs comprising (i) an extracellular binding-domain specifically binding an antigen selected from an antigen of the commensal gut microflora and a self-cell surface antigen specific to the lamina propria (LP) or submucosa of the gastrointestinal tract; (ii) a transmembrane domain; (iii) an intracellular domain including at least one signal transduction element that activates and/or co-stimulates a T cell; and optionally (iv) a stalk region linking the extracellular domain and the transmembrane domain. Compositions and vectors comprising the nucleic acid molecules encoding the aCAR as well as methods for preparing regulatory T cells comprising the vectors and expressing the aCARs are further provided as are methods for treating or preventing a disease, disorder or condition manifested in excessive activity of the immune system in a subject, comprising administering to said subject the mammalian Treg expressing on its surface an aCAR. The regulatory T cells optionally express a membrane-bound homodimeric IL-10 conferring a stable Tr1 phenotype.

The present disclosure provides proteinaceous complexes, pharmaceutical compositions, medicaments and/or kits comprising the proteinaceous complexes, methods for producing the proteinaceous complexes, and uses thereof.

Embodiments of the present disclosure pertain to modified antigen presenting cells that include a recombinant protein appended onto a surface of the antigen presenting cells. The recombinant protein can include: an ectodomain positioned on the surface; a transmembrane domain with a region embedded in the cell membrane; an antigen presenting cell recruiting domain that directs the cells towards the cancer cells; and an antigen presenting cell activator that activates or licenses the antigen presenting cells. Additional embodiments of the present disclosure pertain to methods of expressing the recombinant proteins on antigen presenting cells and utilizing the modified antigen presenting cells for treating various cancers in various subjects. Further embodiments of the present disclosure pertain to nucleotide-containing carriers for expressing the recombinant proteins of the present disclosure in antigen presenting cells.

Abstract: The present disclosure relates, in general, to muteins of IL-10 that are stable as monomers, antigen binding proteins that bind to TREM-1, and antigen binding proteins comprising IL-10 muteins and antigen binding moieties, e.g., anti-TREM-1 antibodies, and compositions thereof. The disclosure also provides methods of treating inflammatory disease, such as inflammatory bowel disease or ulcerative colitis, using the compositions.

This invention relates to fusion proteins, nucleic acid molecules, DNA constructs, and pharmaceutical compositions comprising the same, and methods of their use in IL10 antagonism.

Provided herein, in some embodiments, are artificial secretion peptides capable of directing secretion from Lactobacillus for use, for example, in producing heterologous proteins, including therapeutic proteins.

Provided are improved antibodies, or antigen-binding fragments thereof, which specifically bind to a denatured human collagen polypeptide at a cryptic collagen epitope (anti-denatured collagen antibodies), and fusion proteins comprising anti-denatured collagen antibodies fused to an effector domain, such as a cytokine or an immunomodulatory antibody.

The present disclosure provides antibody cytokine engrafted proteins that bind to and stimulate intracellular signaling through interleukin 10 receptor. Provided antibody cytokine engrafted proteins find use in enhancing anti-inflammatory cell responses, and reducing pro-inflammatory effects in the treatment, amelioration and prophylaxis of immune related disorders. Additionally provided are polynucleotides and vectors that encode antibody cytokine engrafted proteins and host cells capable of producing antibody cytokine engrafted proteins, as well as methods of combining antibody cytokine engrafted proteins with other therapeutics in treating immune related disorder.

The invention is concerned with a fusion protein comprising interleukin 13 and a regulatory cytokine, for example, an interleukin chosen from interleukin 4, interleukin 10, interleukin 27, interleukin 33, transforming growth factor beta 1, transforming growth factor beta 2, and interleukin 13, a nucleic acid molecule encoding such fusion protein, a vector comprising such nucleic acid molecule, and a host cell comprising such nucleic acid molecule or such vector. The invention further pertains to a method for producing such fusion protein. The fusion protein or a gene therapy vector encoding the fusion protein may be used in the prevention or treatment of a condition characterized by pathological pain, chronic pain, neuro-inflammation and/or or neurodegeneration.

A composition including an immunoconjugate and a chemotherapeutic agent. The immunoconjugate includes 1) one or more interleukins, and 2) an Fc domain consisting of a first Fc subunit and a second Fc subunit. The first Fc subunit associates with the second Fc subunit to form a dimer. The one or more interleukins are fused to the Fc domain and the chemotherapeutic agent includes a fluorouracil and/or an oxaliplatin.
