Provided is a new application of a chemokine receptor CCR6 inhibitor in preventing the recurrence of psoriasis. Specifically, provided is a use of the chemokine receptor CCR6 inhibitor for preparing a preparation or composition that is administered to a subject so as to prevent the recurrence of psoriasis in the subject. Also provided is a pharmaceutical product that prevents the recurrence of psoriasis. Using the provided drug products may effectively prevent or alleviate the recurrence of psoriasis.

The invention relates to methods for treating COVID-19 by targeting the inflammasome/caspase1/pyroptosis axis as a key inflammatory pathway. In particular, the invention relates to treating a patient infected with SARS-CoV-2 with an effective amount of one or more compounds that directly or indirectly inhibit one or more pathways of the inflammasome/caspase1/pyroptosis axis.

Disclosed are means, methods and compositions of matter useful for treatment of lung inflammation associated with viral and bacterial infections, as well as with systemic inflammation, through administration of umbilical cord blood derived plasma-based compositions. In one embodiment the invention teaches administration of umbilical cord blood plasma together with pterostilbene, and/or sulforaphane, and/or thymoquinone, and/or Epigallocatechin gallate (EGCG) and/or n-acetylcysteine in an aerosolized manner to patients suffering from COVID-19 associated pulmonary deficiencies. In another embodiment, umbilical cord blood plasma is administered with immune stimulatory agents in order to concurrently inhibit propagation of viral load in the lung while suppressing pulmonary deficiencies.

The present invention is directed to novel PD-1-targeted IL-15/Rα-Fc fusion proteins comprising an IL-15/IL-15Rα Fc-fusion protein and a PD-1 antigen binding domain. The PD-1-targeted IL-15/Rα-Fc fusion proteins can be administered to a patient to treat cancer.

Provided methods of using FLT3L-Fc fusion proteins, including doses and dosing regimens and schedules for administering FLT3L-Fc fusion proteins to a subject in need thereof.

Some embodiments of the invention include methods for treating an animal for a disease comprising one or more administrations of one or more compositions comprising (a) a TNF signaling inhibitor, (b) a CD40 inhibitor, a FAS signaling inhibitor, or both, and (c) optionally, a caspase 8 inhibitor. Other embodiments include methods for treating the disease comprising one or h more administrations of one or more compositions comprising (a) the TNF signaling inhibitor and (b) the CD40 inhibitor. Certain embodiments include methods for treating the disease comprising one or more administrations of one or more compositions comprising (a) the TNF signaling inhibitor, (b) the FAS signaling inhibitor, and (c) optionally, the caspase 8 inhibitor. Still other embodiments include methods for treating a human for autoimmune disease, T cell mediated autoimmune disease, IL-1β mediated autoimmune disease, or cytokine release syndrome. Additional embodiments of the invention are also discussed herein.

The present invention relates to a suppressor or inhibitor of the expression and/or the activity of Chitinase 3-like 1 (CHI3L1) for use in the prevention and/or treatment of tumors, wherein said tumors are resistant to antibody-dependent cell-mediated cytotoxicity (ADCC) dependent therapies and/or for use in reducing the risk of developing resistance to antibody-dependent cell-mediated cytotoxicity (ADCC) dependent therapies.
