Human monoclonal antibodies directed against B7-H1 and uses of these antibodies in diagnostics and for the treatment of diseases associated with the activity and/or expression of B7-H1 are disclosed. Additionally, hybridomas or other cell lines expressing such antibodies are disclosed.

In the broadest aspect, the invention provides a composition for and a method of prophylactic and/or therapeatic treatment of a animal/mammal for any viral disease, mixed bacterial and viral infections, bacterial infections, bacterial endotoxins, bacterial exotoxins, autoimmune diseases, and cellular or humoral mediated allergic conditions that is caused by any virus that relies on the maintenance of specific calcium ion concentrations for the post ribosomal RNA synthesis processing of vital protein transistion, transportation and processing of viral structural components by utilizing a therapeutic amount of a blocker selected from the group consisting of a calcium channel blocker, a metabolic thereof, a calmodulin blocker and a metabolite thereof, and a plumaceutical acceptable diluent or carrier: and/or is caused by damage to the animal/mammal by a pathological immune response to antigens.

The invention relates to novel benzodiazepine derivatives with antiproliferative activity and more specifically to novel benzodiazepine compounds of formula (I)-(VI). The invention also provides conjugates of the benzodiazepine compounds linked to a cell-binding agent. The invention further provides compositions and methods useful for inhibiting abnormal cell growth or treating a proliferative disorder in a mammal using the compounds or conjugates of the invention.

An immune preparation includes an immune substance formed by polyinosinic-polycytidylic acid, a non-antibiotic amino compound, polyethyleneimine, and at least one metal ion. The immune preparation does not include any antibiotics to prevent potential side effects. The amino compound may be chitosan oligosaccharide. The immune preparation is suitable for mucosal administration. The mucosal immune preparation facilitates mucosal immunity of human body allowing for the activation and proliferation of various immune cells.

The present invention refers to the use of an extract from chestnut shells (CSE), peeling waste of the chestnut, (fruit of the tree Castanea sativa Mill., European Chestnut), or fractions of said extract, with specific antiviral activity in the treatment and/or prevention of Herpesviridae, Retroviridae, and Coronaviridae infections.

The claimed invention relates to treatment of virus-related respiratory distress, particularly methods for treating such distress by administering a complement inhibitor. The types of virus-related respiratory distress that can be treated according to the invention include acute respiratory distress syndrome and related phenomena, and can be linked to infection by a coronavirus such as SARS-CoV-2. The invention includes administering complement inhibitor, which can be recombinant or purified C1 inhibitor, and administering complement inhibitor in combination with other therapeutics.

A natural composition for medical purposes, more specifically including procyanidins, for use in the prevention or treatment of endothelial inflammation and/or endothelial systemic dysfunction triggered by Corona virus disease 2019 (COVID-19) including symptomatic post-COVID-19 subjects recovering from COVID-19.

A method of non-covalently loading a plant picornavirus is described. The method includes contacting a plant picornavirus in solution with a molar excess of a cargo molecule to load the plant picornavirus with the cargo molecule, and then purifying the loaded plant picornavirus. Examples of cargo molecules include imaging agents, antitumor agents, and antiviral agents. Loaded plant picornaviruses prepared in this manner can be used to delivering cargo molecule to cells.

Novel human interleukin-2 (IL-2) muteins or variants thereof are provided. In particular, provided are IL-2 muteins that have an increased binding capacity for IL-2Rβ receptor and a decreased binding capacity for IL-2Rγ.sub.c receptor, as compared to wild-type IL-2. Such IL-2 muteins are useful, for example, as IL-2 partial agonist and antagonists in applications where reduction or inhibition of one or more IL-2 and/or IL-15 functions is useful (e.g., in the treatment of graft versus host disease (GVHD) and adult T cell leukemia). Also provided are nucleic acids encoding such IL-2 muteins, methods of making such IL-2 muteins, pharmaceutical compositions that include such IL-2 muteins and methods of treatment using such pharmaceutical compositions.

This application relates generally to the production of polypeptides having specific antigen-binding properties of Fv domains, for example, insertable variable fragments of antibodies, and modified α1-α2 domains of NKG2D ligands.
