Microsporidial Attachment and Host Cell Signaling
Microsporidia exploit several targets for binding to host cells. Attachment is known to be an important first step before infection, and by blocking attachment, host cell infection decreases. This project seeks to determine if microsporidia use an ADAM (A Disintegrin And Metalloprotease) like protei...

Microsporidia exploit several targets for binding to host cells. Attachment is known to be an important first step before infection, and by blocking attachment, host cell infection decreases.

To test this, spore adherence assays employed a small, generated peptide that selected the integrin binding domain of the ADAM like protein. Afterwards, spore attachment to cell culture was quantified to determine if the peptide blocked spore attachment to cell monolayers.
