   <dcterms:abstract>The cow dry period is a non-milking interval where the mammary gland involutes and regenerates&#xd;
to guarantee an optimal milk production in the subsequent lactation. Important bottlenecks such&#xd;
as the high risk of intramammary infections complicate the process. Antibiotics have been routinely&#xd;
used as a preventive treatment but the concerns about potential antibiotic resistance open a new&#xd;
scenario in which alternative strategies have to be developed. Matrix metalloproteinase-9 (MMP-9) is&#xd;
an enzyme able to degrade the extracellular matrix, triggering the involution and immune function of&#xd;
cow mammary gland. We have studied the infusion into the mammary gland of MMP-9 inclusion bodies&#xd;
as protein-based nanoparticles, demonstrating that 1.2 mg of MMP-9 enhanced the involution and&#xd;
immune function of the cow mammary gland. However, the comparison of the efects triggered by the&#xd;
administration of an active and an inactive form of MMP-9 led to conclude that the response observed&#xd;
in the bovine mammary gland was mainly due to the protein format but not to the biological activity of&#xd;
the MMP-9 embedded in the inclusion body. This study provides relevant information on the future use&#xd;
of protein inclusion bodies in cow mammary gland and the role of MMP-9 at dry-of.</dcterms:abstract>
