[BioC] How to filter a list of genes by their ontology

After analysing my arrays for differentially expressed genes, I get a list of genes Id. To reduce even more the number of genes in this list, I would like to retain only genes related to the immune system. I've looked for packages dealing with "ontology" but I couldn't find any doing this simple task...
Any idea on what package/function I could use?
Thanks in advance for your help.
