Papilloma-pseudovirus eradicates intestinal tumours and triples the lifespan of Apc mice.

Inducing tumour-specific adaptive immunity, such as cytotoxic T lymphocyte (CTL) response, can result in promising antitumour effect against several human malignancies, especially in combination with immune checkpoint blockade strategies. However, little is known whether activation of innate immunity can lead to direct tumoricidal effect. Here, we develop a papilloma pseudovirus-based oral immunotherapeutic approach that shows strong tumoricidal effects in the gut, resulting in an almost tripled lifespan of Apc mice (an animal model of human intestinal tumorigenesis).

Relapsing-remitting central nervous system autoimmunity mediated by GFAP-specific CD8 T cells.

Multiple sclerosis (MS) is an inflammatory disease of the CNS that causes the demyelination of nerve cells and destroys oligodendrocytes, neurons, and axons. Historically, MS has been thought to be a CD4 T cell-mediated autoimmune disease of CNS white matter. However, recent studies identified CD8 T cell infiltrates and gray matter lesions in MS patients.

Cellular basis of tissue regeneration by omentum.

The omentum is a sheet-like tissue attached to the greater curvature of the stomach and contains secondary lymphoid organs called milky spots. The omentum has been used for its healing potential for over 100 years by transposing the omental pedicle to injured organs (omental transposition), but the mechanism by which omentum helps the healing process of damaged tissues is not well understood. Omental transposition promotes expansion of pancreatic islets, hepatocytes, embryonic kidney, and neurons.

Pathogenic CD8 T cells in multiple sclerosis and its experimental models.

A growing body of evidence suggests that autoreactive CD8 T cells contribute to the disease process in multiple sclerosis (MS). Lymphocytes in MS plaques are biased toward the CD8 lineage, and MS patients harbor CD8 T cells specific for multiple central nervous system (CNS) antigens. Currently, there are relatively few experimental model systems available to study these pathogenic CD8 T cells in vivo.

Inhibition of bleomycin-induced pulmonary fibrosis through pre-treatment with collagen type V.

Background: Tolerance to collagen structures has been shown to inhibit the progression of autoimmune scleroderma and rheumatoid arthritis. More recently, tolerance induction to collagen type V (colV) in experimental models of lung transplantation was shown to ameliorate the complex pathology known as "chronic rejection." The link between colV autoimmunity and progressive graft dysfunction and subsequent development of bronchiolitis obliterans syndrome (BOS) has been established in human lung transplant recipients.

Resting B cells expand a CD4+CD25+Foxp3+ Treg population via TGF-beta3.

Regulatory T cells (Treg) play critical roles in maintaining tolerance and preventing autoimmunity. It is not fully clear how these cells are generated and maintained. Here, we show that resting B cells are able to expand Treg.

Tumor resistance to CD8+ T cell-based therapeutic vaccination.

CD8(+) cytotoxic T lymphocytes (CTLs) play an important role in antitumor immunity. Induction of tumor-specific CTLs is one major strategy for tumor immunotherapy. However, therapeutic vaccinations used to treat firmly established tumors are generally ineffective.
