Background: Histamine fixed-immunoglobulin formulations, which consisted of 0.15 µg of histamine dihydrochloride and 12 mg of human immunoglobulin in a vial, are used for anti-allergic treatments, and controlling the amounts of histamine in the formulations is essential to avoid histamine intoxication.

Objective: A high-performance liquid chromatography (HPLC) method for determination of histamine contents of the formulations was established and validated.

Purpose: To evaluate the detailed immunosuppressive role(s) of PD-L2 given that its detailed role(s) remains unclear in PD-1 signal blockade therapy in animal models and humans.

Experimental Design: We generated mouse cell lines harboring various status of PD-L1/PD-L2 and evaluated the tumor growth and phenotypes of tumor-infiltrated lymphocytes using several PD-1 signal blockades in animal models. In humans, the correlation between immune-related gene expression and (encoding PD-L1) or (encoding PD-L2) was investigated using The Cancer Genome Atlas (TCGA) datasets.

Background: Recently, it has been reported that Th17 contributes to allograft rejection after transplantation. We investigated the alteration of Th17 and regulatory T cells (Treg) distribution in an animal model of bronchiolitis obliterans following ectopic tracheal transplantation model.

Methods: Tracheal grafts from B6 mice transplanted into subcutaneous sites of C3H mice.
