Provided herein is a method and kit for diagnosing and treating Graft versus host disease (GVHD), the method including obtaining a body fluid or tissue sample from said mammal, throughout the year post-transplant; detecting the expression level, phosphorylation level, or a combination thereof, of biomarkers in said body fluid or tissue sample; diagnosing said mammal with Graft versus host disease (GVHD) when the expression level, phosphorylation level, or a combination thereof of said biomarkers in said body fluid or tissue sample are detected with a deviation of at least about 25% from standard measurements taken from healthy subjects and/or from measurements taken from said mammal prior to said transplant; and, administering an effective amount of at least one immunosuppressant or steroid or a combination thereof to the diagnosed mammal.

Aspects of the disclosure relate to antibodies that bind to transferrin receptor (e.g., transferrin receptor 1) and complexes comprising the antibody covalently linked to a molecular payload. Methods of using the antibodies are also provided.

Provided in the present invention is an isolated anti-CD22 antibody or an antigen-binding fragment thereof, and further provided is the use thereof. The antibody or the antigen binding fragment thereof shows strong identification capability for and a high affinity to CD22 recombinant protein and a CD22 positive cell line, a strong internalization capability to enter the CD22 positive cell line, and an effective growth inhibition and cell apoptosis effect on the CD22 positive cell line after fusion with bacterial exotoxin.

An immunogenic product including at least one immunoglobulin or fragment thereof conjugated with a carrier protein, wherein the at least one immunoglobulin is IgE and preferably wherein the IgE fragment includes the IgE Cε3 domain, and wherein the carrier protein is preferably CRM.sub.197. Also the use of this immunogenic product for treating inflammatory disorders, and in particular allergic disorders.

The present disclosure belongs to the field of the use of liposome preparations in the preparation of tumor drugs, and in particular, relates to the construction and use of a multicellular targeting liposome. Due to that a single liposome includes multiple antibodies against different cells, and a liposome with a stable structure and long circulation characteristics in vivo is constituted by molecular self-assembly, the multicellular targeting liposome can sequentially or simultaneously bind to multiple different cells by means of the action of antibodies to promote the identification of, communication between, the cytotoxicity of, the pro-apoptosis or clearance of different cells, etc.

A method of making coated avian egg yolk cores includes providing dried avian egg yolk cores having a diameter of 100 to 1500 micrometers, applying avian egg albumen to the dried avian egg yolk cores to provide the coated avian egg yolk cores, and optionally drying the coated avian egg yolk cores, wherein the ratio of dry avian egg albumen to dried avian egg yolk in the coated avian egg yolk cores is 1:10 to 10:1. Also included are the coated avian egg yolk cores, food and feed additives containing the coated avian egg yolk cores and food and feed compositions containing the coated avian egg yolk cores.

Methods of delivering therapeutic agents by administering compositions including a bacterial collagen-binding polypeptide segment linked to the therapeutic agent to subjects in need of treatment with the therapeutic agent are provided. In these methods, the therapeutic agent is not a PTH/PTHrP receptor agonist or antagonist, basic fibroblast growth factor (bFGF) or epidermal growth factor (EGF). The bacterial collagen-binding polypeptide segment delivers the agent to sites of partially untwisted or under-twisted collagen. Methods of treating collagenopathies using a composition including a collagen-binding polypeptide and a PTH/PTHrP receptor agonist are also provided. In addition, methods of treating hyperparathyroidism, and hair loss using compositions comprising a collagen binding polypeptide and a PTH/PTHrP receptor agonist are provided. Finally, methods of reducing hair regrowth by administering a composition including a collagen binding polypeptide and a PTH/PTHrP receptor antagonist are provided.
