The present invention relates to novel regulatory T cell proteins. One protein, designated PD-L3, resembles members of the PD-L1 family, and co-stimulates αCD3 proliferation of T cells in vitro. A second, TNF-like, protein has also been identified as being upregulated upon αCD3/αGITR stimulation. This protein has been designated T.sup.reg-sTNF. Proteins, antibodies, activated T cells and methods for using the same are disclosed.

In particular methods of using these proteins and compounds, preferably antibodies, which bind or modulate (agonize or antagonize) the activity of these proteins, as immune modulators and for the treatment of cancer, autoimmune disease, allergy, infection and inflammatory conditions, e.g. multiple sclerosis is disclosed

Provided herein are methods and compositions related to Prevotella bacteria for the reduction of IL-8, IL-6, IL-Iβ, and/C or TNFα expression and/or for the treatment of viral infections.

A method for assessing the potency of MSCs to produce anti-inflammatory cytokines in response to a pro-inflammatory stimulus. The method comprises stimulating the MSCs with one or more proinflammatory cytokines, such as TNF-α, for a duration of time and then identifying and quantifying the production of anti-inflammatory cytokines. MSCs that produce potent levels of anti-inflammatory cytokines in response to TNF-α can be used in treatments for aging-related conditions, including aging frailty and Alzheimer's disease, and can also be used to treat corona virus infections. The method shows that TNF-α induced MSCs robustly secrete several anti-inflammatory cytokines, including IL-1 receptor antagonist (IL-1RA), IL-10, and granulocyte colony stimulating factor (G-CSF).

The present invention provides compounds and methods targeting human interleukin-19, including therapeutic antibodies, pharmaceutical compositions and diagnostic applications useful in the field of immune-mediated diseases including psoriasis, atopic dermatitis, psoriatic arthritis, bronchial asthma and diabetic nephropathy.

Biomarkers are provided that are associated with or predictive of a subject's responsiveness to a JAK inhibitor. The biomarkers, compositions, and methods described herein are useful in selecting appropriate treatment modalities for a subject having, suspected of having, or at risk of developing vitiligo.

A method for assessing a suicidal severity in a depressed patient according to an embodiment includes measuring a concentration of a suicidal behavior prediction biomarker contained in a biological sample of the depressed patient, wherein the suicidal behavior prediction biomarker is one or more markers selected from the group consisting of cortisol, interleukin-1 beta (IL-1β), homocysteine, total cholesterol, and folate, and determining a probability of an increased suicidal severity by comparing the measured concentration of the suicidal behavior prediction biomarker with a preset cutoff level thereof.

A method for predicting antidepressant treatment response and acute prognosis for depressed patients according to an embodiment of the present disclosure includes measuring a concentration of an antidepressant treatment response prediction biomarker contained in a biological sample of a depressed patient at baseline and determining whether there is an acute phase remission, depending on the measured concentration of the antidepressant treatment response prediction marker.

The present invention provides methods of treating inflammation associated with infection, and methods of preventing or reducing the severity of sepsis caused by inflammation associated with infection, in an individual comprising, consisting essentially of or consisting of the steps of administering a therapeutically effective amount of idronoxil, or derivative, pharmaceutically acceptable salt, ester, amide, polymorph and/or prodrug thereof to the individual, wherein the individual is diagnosed with, or suspected of having, early stage organ damage caused by inflammation associated with infection.

[Problem]

To find a method having higher stability, reproducibility, economic efficiency, and operation easiness in an evaluation method of safety of a substance in vitro, by using human immortalized myeloid cells.

[Solving Means]

A method for evaluating the skin sensitizing property and/or the pyrogenic property of a test substance, a method for detecting a skin sensitizer and/or a pyrogen in a sample, and a method for evaluating the action of a sample on a function of immune cells, each using human immortalized myeloid cells and including measuring the production amount of IL-6 and/or IL-8 in a culture medium of human immortalized myeloid cells.

Provided are methods for aiding in diagnosis and treatment of non-small cell lung cancer (NSCLC) adenocarcinoma. The methods involve determining elevated circulating Interleukin-18 (IL-18) values to aid in the diagnosis and treatment of NSCLC. Medical interventions based on determining circulating IL-18 levels are provided and include additional scanning, surgical resection of tumors, and administration of adjuvant therapy, such as chemotherapy or immune therapy.
