Evolution of DNA ploidy during squamous cell carcinogenesis in the esophagus

Image and flow cytometry was used to study the nuclear DNA content (ploidy) during the squamous cell carcinogenesis in the esophagus. The present retrospective study comprised 26 surgical specimens of squamous cell carcinomas (SCC) in patients who underwen ...

Differential T cell function and fate in lymph node and nonlymphoid tissues

Nicola Harris

The functions and fate of antigen-experienced T cells isolated from lymph node or nonlymphoid tissues were analyzed in a system involving adoptive transfer of in vitro-activated T cells into mice. Activated T cells present in the lymph nodes could be stimu ...

Role of extracellular matrix assembly in interstitial transport in solid tumors

Melody Swartz

The extracellular matrix (ECM) may contribute to the drug resistance of a solid tumor by preventing the penetration of therapeutic agents. We measured differences in interstitial resistance to macromolecule (IgG) motion in four tumor types and found an une ...

Inducible chromosomal translocation of AML1 and ETO genes through Cre/loxP-mediated recombination in the mouse

Transgenic mice have been used to explore the role of chromosomal translocations in the genesis of tumors. But none of these efforts has actually involved induction of a translocation in vivo. Here we report the use of Cre recombinase to replicate in vivo ...

Transgenic mouse models for tumors of melanocytes and retinal pigment epithelium

Friedrich Beermann

Cutaneous and ocular melanomas are due to malignant transformation of neural crest-derived melanocytes. The rising incidence of this tumor in humans has stimulated experiments to devise suitable mouse models. In the past years, transgenic mouse lines have ...

Demonstration of an interferon gamma-dependent tumor surveillance system in immunocompetent mice

Michel Aguet

This study demonstrates that endogenously produced interferon gamma (IFN-gamma) forms the basis of a tumor surveillance system that controls development of both chemically induced and spontaneously arising tumors in mice. Compared with wild-type mice, mice ...

Long circulating half-life and high tumor selectivity of the photosensitizer meta-tetrahydroxyphenylchlorin conjugated to polyethylene glycol in nude mice grafted with a human colon carcinoma

Hubert van den Bergh, Georges Wagnières

In a model of nude mice bearing a human colon carcinoma xenograft, the biodistribution and tumor localization of metatetrahydroxyphenylchlorin (m-THPC) coupled to polyethylene glycol (PEG) were compared with those of the free form of this photosensitizer u ...

Blockade of CD28/B7 co-stimulation by mCTLA4-Hgamma1 inhibits antigen-induced lung eosinophilia but not Th2 cell development or recruitment in the lung

Nicola Harris

We have studied the role of the CD28/B7 co-stimulatory pathway in the development of a Th2-type lung immune response. Mice injected two or three times intraperitoneally with ovalbumin in alum adjuvant and then re-exposed to the same antigen by intranasal ( ...

CD80 costimulation is essential for the induction of airway eosinophilia

Nicola Harris

CD80 and CD86 (B7-1 and B7-2) are the ligands on antigen-presenting cells (APCs) which bind CD28 and deliver the costimulatory signals necessary for T cell activation. The reasons for the existence of two CD28 binding molecules are not well understood. We ...

Neurons induced to express major histocompatibility complex class I antigen are killed via the perforin and not the Fas (APO-1/CD95) pathway

Daniel Constam

Cytotoxic T lymphocytes (CTL) kill target cells by perforin-mediated pore formation, induction of apoptosis by the Fas ligand, or both. It has been demonstrated that depolarized neurons can be induced to express major histocompatibility complex (MHC) class ...
