Glomerular filtration is one of the primary functions of the kidney. Podocytes, a highly specialized cell type found in glomeruli, are believed to play a critical role in that function. Null mutations of genes expressed in podocytes like WT1, nephrin, and NEPH1 result in an embryo and perinatal lethal phenotype and therefore do not allow the functional analysis of these genes in the adult kidney. Here is describes the generation of a model that will allow such studies. We have engineered transgenic mice in which the disruption of targeted genes can be induced in a temporally controlled fashion in podocytes. For this, a transgene encoding the mutated estrogen receptor-Cre recombinase fusion protein was introduced into the mouse genome. Animals were crossed with Z/AP reporter mice to test for efficient and inducible recombination. We found that, after injection of inducer drug tamoxifen, Cre fusion protein translocates to the nuclei of podocytes, where it becomes active and mediates recombination of DNA carrying loxP target sequences. These animals provide for the first time a tool for silencing genes selectively in podocytes of adult animals.

It is widely accepted that a strong Th2 response is responsible for nonhealing Leishmania major infections in BALB/c mice. This Th2 response has been thoroughly documented by measuring the levels of Th2 cytokines produced by CD4(+) T cells present in the lymphoid organs by enzyme-linked immunosorbent assay and PCR. However, the cytokine profile of L. major-specific Th2 cells has never been determined. In this study, we used the recently described Th2 marker T1/ST2 to characterize Th2 cells during the course of nonhealing L. major infection. We analyzed the intracellular cytokine profile of CD4(+) T1/ST2(+) T cells and showed that they clearly displayed a Th2 phenotype, as they expressed interleukin 4 (IL-4), IL-10, and IL-5. In addition, we detected another population of Th2 cells among the CD4(+) T1/ST2(-) T cells that expressed IL-4 and IL-10 but excluded IL-5. In summary, we show here that two type 2 subpopulations are present in the lymphoid organs of L. major-infected BALB/c mice; Th2 cells from both subsets expressed IL-4 and IL-10, but they could be distinguished by their expression of IL-5 and T1/ST2.

Classically, mouse embryonic stem (ES) cells are transfected by electroporation, a method that requires a large number of cells. Here we describe a protocol using a liposome based transfection agent that is a very simple, rapid and cost effective way of transiently transfecting very low numbers of ES cells. We found this method very useful in screening a large number of ES clones when working with inducible expression systems in which at least two elements are required for regulated expression of the gene of interest. After stable transfection of the first component, clones can be easily and rapidly screened for expression of the gene of interest by transiently transfecting the second component of the system using this protocol.
