Provided are a psoriasis-induced transgenic animal model overexpressing the Pellino homolog 1 (Peli1) gene according to doxycycline administration, and a use thereof. The transgenic animal model of the present disclosure exhibited similarity to phenotypes shown in patients with psoriasis, due to overexpression of the Pellino homolog 1 (Peli1) gene according to doxycycline administration. It is anticipated that the transgenic animal model may be usefully used in clinical studies, such as screening for a candidate drug for the treatment of psoriasis. Additionally, it is anticipated that a peptide derived from the Peli1 FHA domain targeting the FHA binding motif that inhibits normal substrate binding between a substrate protein and the Peli1 protein may be usefully used in the development of new drugs for psoriasis-associated diseases. Moreover, by confirming an expression level of the Peli1 protein, it is anticipated to be usefully used in evaluating the severity of patients with psoriasis.

Provided are an expression inhibitor of an inflammation promoting factor based on the discovery of a new factor influencing the expression amount/level of an inflammation promoting factor, and a development tool therefor. Provided are also a diagnostic agent and a diagnosis method for immune diseases, inflammatory diseases, painful conditions and similar. More specifically provided are: an expression inhibitor of an inflammation promoting factor containing at least one kind of inhibitor selected from the group consisting of RBMS2 expression inhibitor and RBMS2 function inhibitor; a screening method using as an indicator the expression or the function of RBMS2; an expression cassette useful for said method; as well as a diagnostic agent containing a product detection agent for RBMS2 gene expression and disease detection method using as an indicator RBMS2 gene expression amount/level.

This invention provides methods of treating androgenetic alopecia (AGA), acne, rosacea, prostate cancer, and benign prostatic hypertrophy (BPH), comprising the step of contacting a subject with a compound or composition capable of decreasing prostaglandin D2 (PGD2) level or activity, a downstream signaling or receptor pathway thereof, or prostaglandin D2 synthase level or activity; methods of stimulating hair growth, comprising the step of contacting a subject with a compound or composition capable of increasing or decreasing the activity or level of a target gene of the present invention, or with a protein product of the target gene or an analogue or mimetic thereof; and methods of testing for AGA and evaluating therapeutic methods thereof, comprising measuring PGD2 levels.

The present invention provides compositions and methods for treating joint disorders that are characterized by an inflammatory component. In some aspects, the compositions and methods are to prevent the progression of osteoarthritis and other arthritides and to treat osteoarthritis and other arthritides in a mammalian joint.

Disclosed is a non-human animal comprising a genetic construct expressing TCR and TCR genes and wherein the animal comprises a null-mutated Rag-2 locus. Described herein is also a NOD.Rag2.sup./ mouse expressing a transgenic , T cell receptor. The animals spontaneously develop chronic inflammation and fibrosis, and are useful as animal models of fibrotic disease.

Provided herein, inter alia, are non-human animals comprising nucleic acid sequences encoding a C3 protein that comprises a human sequence as well as transgenic non-human animals comprising a C3 gene that is human in whole or in part as well as methods for using the same to screen for candidate therapeutic molecules to treat complement-related nephropathies. Also provided herein are methods for improving kidney function in an individual diagnosed with or thought to have a complement-related nephropathy.

The present invention provides a method for detection of an inflammatory reaction, which comprises using a transformant or transgenic non-human animal transfected with a vector comprising a promoter for a gene encoding an inflammatory cytokine, a gene encoding a reporter protein, a gene encoding the inflammatory cytokine, and a gene encoding a proteolytic signal sequence to thereby detect an inflammatory reaction induced upon inflammatory stimulation in the transformant or in the transgenic non-human animal.

The subject matter disclosed herein is generally directed to methods and compositions for modulating inflammation driven by differentiation of quiescent tissue-resident ILCs into a spectrum of pathogenic effectors. The subject matter disclosed herein is also generally directed to detecting and monitoring an ILC response. Additionally, the subject matter is directed to treating skin inflammation, such as psoriasis.

A transgenic cat with a phenotype characterized by the substantial absence of the major cat allergen, Fel d I. The phenotype is conferred in the transgenic cat by disrupting the coding sequence of the target gene with a specialized construct. The phenotype of the transgenic cat is transmissible to its offspring.

Provided is a method for inducing regulatory T cells, comprising a step of inhibiting the expression of Satb1 or the function of Satb1 in peripheral conventional T cells.
