Software licensing issues your company may have been experiencing, just became a lot easier today just by reading this article.

A superb software licensing management tool, aptly and simply called the Reprise License Manager (RLM) from a company called Reprise Software based in San Jose, California, will dispense with the issue of site managers being responsible for auditing and purchasing software license agreements (or forgetting to as is sometimes the case).

Dispensing with the prospect of running illegal, unlicensed software on any site or location the company operates from, the prospect of unlicensed software and software protection becomes a thing of the past.

Software vendors and developers spend many millions of dollars on development, especially if the software is an operating system, email server or client application, or indeed antivirus software.

The cyber world is a dangerous place, and software licensing and the fees one’s company pays for having genuine software, is the guaranteed method of ensuring your company’s servers, computers and networks, as well as all of the various applications running on them are not susceptible to malicious attacks.

The RLM software license management tool is a very flexible package, and is easily adapted to the specific need of the client company, offering users advanced features such as activation over the Internet, distributed license servers, access prioritization to software, access guarantees for critical users, and secured encryption of licenses.

Once the RLM application has been purchased from Reprise Software, it is easy to implement and indeed fast, with a single Application Programming Interface (API) that provides for management of licenses on Linux and Unix operating platforms, Windows and the Mac OS, X and Java.

The modern architecture can be taken advantage of to insulate and protect end users from the complex issues surrounding advanced software license management.

Companies as diverse as Schlumberger, Tektronix and CMG, the Computer Modelling Group already use the advanced management system RLM from Reprise Software.

And by the very power of the servers and networks in use today, it doesn’t matter where your company is based, in the US or overseas.

The very power of the internet enables this software to be available instantly, and impart software licensing peace of mind in a rapidly changing environment.

For complete software licensing management system software with the power to solve all your software management issues, and to see for yourself the service, not to mention the auditing power Reprise Software can impart to your company, visit them at their website www.reprisesoftware.com today.

CCL21 is a small cytokine that binds to the chemokine receptor CCR7. It is thought to inhibit haemopoiesis and stimulate chemotaxis, in vitro antibody studies having shown CCL21 to be selectively chemotactic for activated T-cells and thymocytes. It may also have a role in lymphocyte migration to secondary lymphoid organs. We at Novus Biologicals have nine CCL21 antibodies on our antibody database.

Tumour growth is dependent on the cells’ ability to evade attack by the host’s immune system. In 2007, G.A Rabinovich et al published a paper suggesting tumour cells employ a number of strategies for this, including activation of negative regulatory pathways and secretion of immunosuppressive agents. In the same year, Shields et al published a paper showing CCL21 to be secreted by certain tumour cells. Now, they have published a new study showing a novel mechanism by which CCL21-secreting cells actively alter their outer morphology, presenting a lymphoid-like surface that promotes evasion of the immune response by creating a tolerant stromal microenvironment.

Using a shRNA (small hairpin RNA) and lentiviral transduction techniques, mouse melanoma cell sublines were created expressing varying amounts of CCL21. CCL21 secretion was either upregulated (CCL21+) down regulated (CCL21-) or left unchanged as a control. The resultant sublines were then transplanted into normal syngeneic mice. Examination of the resultant tumours revealed that CCL21+ tumours were markedly larger than those from the CCL21- group. Furthermore, CCL21-secreting tumours had reorganised their microenvironment to resemble lymphoid tissue.

Several factors pointed to this. Firstly, LTi (lymphoid tissue-induced) cells were found in all tumours except those expressing low CCL21 levels. LTi cells are integral to normal lymphoid tissue, promoting localised expression of chemokines from stromal cells such as FRCs (fibroblast-like reticular cells). Additionally, antibody assays indicated the presence of gp38, ER-TR7 and PNAd stromal lymphoid cell markers in the stroma of CCL21+ tumours, but not those of CCL- lines.

Although lymphoid tissue is associated with activation of the immune response, it is also known to suppress it under normal conditions. The CCL21-secreting tumours recruited immune suppressors associated with normal lymphoid tissue; further CCL21 antibody research will examine the pathways involved. Our antibody catalogue at Novus Biologicals is often used for immune response research.
