Apologies about the mixup, the active projects doesn't support easy viewing unless you click on them one by one. My guess is that perhaps those scientists researching those diseases aren't active at the moment or require some other forms of research before they need to use the folding mechanisms provided by FaH.
Maybe one of the active projects do have some relevance to those targets but folding@home seems to have become a resource that helps science in general and updates can be sparce especially in providing information towards folders about what the scientists are doing unless it is an amazing update like "we cured cancer" or something super special.
If it does become active again and you are looking to support fighting those diseases the advanced ui also gives the choice to specify the disease you wish to fight under the "cause preference" title in the advanced tab of the configure section
