A method of treating an RNA virus infection in a subject in need that includes administering a therapeutically effective amount of a heparanase inhibitor. The RNA virus includes SARS-CoV-1, SARS-CoV-2, HTLV-1, HIV-1, and any combination thereof. The heparanase inhibitor includes heparin, a heparin mimetic, or any combination thereof. In some aspects, the heparanase inhibitor is Roneparstat. In some aspects, the administration of the therapeutically effective amount of the heparanase inhibitor results in the inhibition of infection by the RNA virus and associated inflammatory cytokine production.

The present invention relates to methods and materials for modulating the complement alternative pathway (CAP), the complement classical pathway (CCP), the complement lectin/mannose pathway (CMP), or combinations thereof, as well as methods and materials for targeting diagnostic, prophylactic and therapeutic agents to localized areas of tissue within the body where they may more directly exert their effects upon the intended target cells or tissue, with reduced, associated systemic effects compared with administration of the same or similar agents in an untargeted, systemic manner. The methods and materials of the present invention may therefore allow for increased efficacy, lower threshold effective dosages and/or lower effective maintenance doses, and/or reduced associated undesired or adverse effects in terms of frequency or severity of occurrence, or both. The present invention also relates to methods and materials for modulating a host humoral immune response, especially reducing, inhibiting, or preventing a host humoral immune response.

The present invention provides means and methods for treating Interleukin 18 (IL-18)-associated diseases and disorders. In particular, the present invention discloses antibodies specific for free IL-18 and IL-18 Binding Protein (IL-18BP) for use in such treatments and for the diagnosis of the indications.

The present disclosure provides compositions and methods for efficient and effective protein delivery in vitro and in vivo. In some aspects, proteins are reversibly crosslinked to each other and/or modified with functional groups and protected from protease degradation by a polymer-based or silica-based nanoshell.

A compound of formula (I) or a pharmaceutically acceptable salt, or N-oxide thereof and the use of the same in therapy: wherein Z, Y, R.sup.1, W, V, and R.sup.3 are as defined in claim 1. ##STR00001##

The present disclosure relates to compositions and methods for using cells having chemically-induced fusion protein complexes to spatially and temporally control immune cell signal initiation and downstream responses for treating disease. As a preferred example, the present disclosure relates to fusion polypeptides comprising (a) a first polypeptide comprising a first secretion signal, a first multimerization domain, a first transmembrane domain, and an actuator domain, (b) a viral self-cleaving polypeptide, and (c) a second polypeptide comprising a second secretion signal, a binding domain that comprises a single chain antibody, a receptor ectodomain, or a ligand, a second multimerization domain, and a second transmembrane domain.

The invention provides anti-cluster of differentiation 3 (CD3) antibodies and methods of using the same.

The present disclosure provides improved genome editing compositions and methods for editing a TGFβR2 gene. The disclosure further provides genome edited cells for the prevention, treatment, or amelioration of at least one symptom of, a cancer, an infectious disease, an autoimmune disease, an inflammatory disease, or an immunodeficiency.

The present invention relates to a method of treating acute or chronic systemic graft-versus-host disease (GVHD) with extracellular vesicles, e.g., exosomes obtained from human cardiospheres or cardiosphere-derived cells (CDCs), wherein systemic GVHD involves, e.g., at least two organs selected from the group consisting of the skin, mucosa, gastrointestinal tract, liver, lungs, joints and fascia, genitalia, and eyes. The present invention also provides a pharmaceutical formulation comprising extracellular vesicles, e.g., exosomes obtained from human cardiospheres or CDCs, for systemic administration, e.g., intravenous infusion, to a human subject in need of treatment of systemic GVHD.
