Provided herein are methods for the treatment of viral infections and inflammation secondary to viral infections (e.g., coronavirus infections (e.g., severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), etc.) and diseases (e.g., Coronavirus disease 2019 (COVID-19)) associated therewith by the administration of low doses of tocilizumab to a subject. In particular embodiments, provided herein are pharmaceutical compositions comprising doses of 200 mg or less of tocilizumab and methods for the treatment of SARS-CoV-2 infections, COVID-19, inflammation secondary to such infections, and symptoms or other conditions arising as a result thereof.

Biomarkers useful for diagnosing and assessing inflammatory disease are provided, along with kits for measuring their expression. The invention also provides predictive models, based on the biomarkers, as well as computer systems, and software embodiments of the models for scoring and optionally classifying samples. The biomarkers include at least two biomarkers selected from the DAIMRK group and the score is a disease activity index (DAI).

The invention provides methods, kits and reagents for diagnosing fibromyalgia (FM) in an individual by determining whether the levels of one or more cytokines in the individual are altered, as compared to control levels. The altered level(s) or patterns of expression of the cytokines measured in the affected individual compared to the level from the control is predictive/indicative of FM in the individual.

The present inventors discovered that problems of existing antibody pharmaceuticals can be solved by producing antigen-binding molecules that contain an antigen-binding domain whose antigen-binding activity varies depending on the concentration of a target tissue-specific compound. Use of antigen-binding molecules of the present invention enables various diseases that originate from a target tissue to be treated in a manner specific to the target tissue.

Provided herein are biomarkers for the treatment of pathological conditions, such as cancer, and method of using PD-1/PD-L1 pathway antagonists. In particular, provided are biomarkers for patient selection and prognosis in cancer, as well as methods of therapeutic treatment, articles of manufacture and methods for making them, diagnostic kits, methods of detection and methods of advertising related thereto.

Some embodiments are directed to a method for the in vitro detection/prediction of imminent childbirth based on the detection of at least two of the following markers: insulin-like growth factor-binding protein 1 (IGFBP-1), a N-terminal fragment of insulin-like growth factor-binding protein 1, and interleukin 6 (IL-6). Some embodiments are also directed to a device for the implementations of the method. Some embodiments are applicable in the medical field, in the diagnostic field, and in particular in the obstetric field.

The disclosure provides, inter alia, methods of detecting IL-6 signaling activity in T cells in breast cancer patients, such as breast cancer patients in remission.

Provided are methods and systems for determining functional relationships between ex vivo skin models and an inflammatory skin condition. Also provided are methods and systems for identifying modulators of inflammation of skin, as well as the use of modulators identified by such methods or systems for the preparation of cosmetic compositions, personal care products, or both.

Described herein are methods and kits for performing plasmon-enhanced fluoro-dot assays. These assays enable observing a correlation between a chemical stimulus and a biological response of cultured cells in vitro.

This disclosure relates to methods of diagnosing and predicting renal disease, using one, two, or more biomarkers, including sTNFR1, sTNFR2, sFAS, TNF, and IL-6.
