Welcome to Wikipedia. Although everyone is welcome to contribute to Wikipedia, at least one of your recent edits, such as the one you made to Cell-mediated immunity with this edit, has been reverted, as it appears to be unconstructive. For constructive edits, always provide an informative edit summary so that editors have a brief description of your intentions. If you want to try out how editing Wikipedia works, please edit the sandbox page and not encyclopedia articles. If you have questions about editing Wikipedia, you might want to take a look at this tutorial. You may also wish to read the introduction to editing. Thank you.  Tide  rolls  23:10, 24 July 2011 (UTC)
