<p>Bovine tuberculosis (bTB) is a zoonotic disease caused by <i>Mycobacterium bovis</i>
that is responsible for significant economic losses worldwide. In spite
of its relevance, the limited knowledge about the host immune responses
that provide effective protection against the disease has long hampered
the development of an effective vaccine. The identification of host
proteins with an expression that correlates with protection against bTB
would contribute to the understanding of the cattle defence mechanisms
against <i>M. bovis</i> infection. In this study, we found that <i>ERAP1</i> and <i>PDE8A</i> were downregulated in vaccinated cattle that were protected from experimental <i>M. bovis</i> challenge. Remarkably, both genes encode proteins that have been negatively associated with immune protection against bTB.</p>
