- The coxsackievirus and adenovirus receptor (CAR) is a cell adhesion molecule expressed in epithelial tight junctions and other cell-cell contacts. Using indirect immunofluorescence, quantitative RT-PCR, and Western blots, the expression and distribution of CAR in developing and adult testis are examined. CAR is highly expressed in both Sertoli and germ cells during perinatal and postnatal development, followed by a rapid down-regulation of both mRNA and protein levels. Interestingly, we find that CAR is a previously unknown downstream target for FSH because CAR mRNA levels were induced in primary cultures of FSH-stimulated Sertoli cells. In contrast to other epithelia, CAR is not a general component of tight junctions in the seminiferous epithelium, and Sertoli cells in the adult testis do not express CAR. Instead, CAR expression is stage dependent and specifically found in migratory germ cells. RT-PCR also demonstrated the presence of junctional adhesion molecule-like (JAML) in the testis. JAML was previously reported by others to form a functional complex with CAR regulating transepithelial migration of leukocytes. The expression of JAML in the testis suggests that a similar functional complex might be present during germ cell migration across the blood-testis barrier. Finally, an intermediate compartment occupied by CAR-positive, migrating germ cells and flanked by two occludin-containing junctions is identified. Together, these results implicate a function for CAR in testis morphogenesis and in migration of germ cells across the blood-testis barrier during spermatogenesis.

- The baculovirus Autographa californica multiple nucleopolyhedrosis virus causes non-productive infection in mammalian cells. Recombinant baculovirus therefore has the capability to transfer and express heterologous genes in these cells if a mammalian promoter governs the gene of interest. We have investigated the possibility of using baculovirus as a tool to produce recombinant adeno-associated virus (rAAV). AAV has become increasingly popular as a vector for gene therapy and functional genomics efforts, although its use is hampered by the lack of a simple and efficient vector production method. We show here that co-infection of mammalian producer cells with three viruses – a baculovirus containing the reporter gene flanked by AAV ITRs, a baculovirus expressing the AAV rep gene and a helper adenovirus expressing the AAV cap gene – produces infectious rAAV particles. This baculovirus-based chimeric vector method may in future improve large-scale rAAV vector preparations and circumvent present-day problems associated with rAAV production.
