Although the blood vessel-specific fluorescent transgenic mouse has been an excellent tool to study vasculogenesis and angiogenesis, a lymphatic-specific fluorescent mouse model has not been established to date. Here we report a transgenic animal model that expresses the green fluorescent protein under the promoter of Prox1, a master control gene in lymphatic development. Generated using an app...

Although the roles of CD8+ T cells and a major preerythrocytic antigen, the circumsporozoite (CS) protein, in contributing protective antimalaria immunity induced by radiation-attenuated sporozoites, have been shown by a number of studies, the extent to which these players contribute to antimalaria immunity is still unknown. To address this question, we have generated C57BL/6 (B6) transgenic (T...

Purpose: To generate a transgenic mouse that when crossed with spontaneous mouse models of lymphoma will allow for quantitative in vivo measurement of tumor burden over the entire spectrum of the disease and or response to therapy in a "disease" or lymphoma subtype-specific manner. Experimental Design: We developed a novel genetically engineered transgenic mouse using a CherryLuciferase fusion ...

Studies in vitro have suggested that a species barrier exists in functional interaction between human histocompatibility leukocyte antigen (HLA) class II and mouse CD4 molecules. However, whether mouse CD4+ T cells restricted by HLA class II molecules are generated in HLA class II transgenic mice and respond to peptide antigens across this barrier has remained unclear. In an analysis of T cell ...

PURPOSE Gene inactivation with homologous recombination in mice is a widely used tool to study gene function. However, many proteins play essential roles in a number of tissues and germline gene inactivation often results in embryonic lethality. To overcome this limitation and to dissect the functions of essential genes beyond embryonic development, we generated mouse rod opsin promoter-control...

A 3233 base pair (bp) sequence of the 5'-flanking region of the mouse cellular retinoic-acid-binding protein (CRABP) gene is determined. From this region, a 3 kb fragment located 150 bp upstream from the transcriptional initiation site is isolated and fused to a LacZ reporter sequence. Transgenic mouse embryos of this fusion gene show spatially and temporally specific expression of LacZ protein...
