Macrophages are classified upon activation as classical activated M1 and M2 anti-inflammatory regulatory populations. This macrophage polarization is well characterized in humans and mice, but M1/M2 profile in cattle has been far less explored. Bos primigenius taurus (taurine) and Bos primigenius indicus (indicine) cattle display contrasting levels of resistance to infection and parasitic diseases such as C57BL/6J and Balb/c murine experimental models of parasite infection outcomes based on genetic background. Thus, we investigated the differential gene expression profile of unstimulated and LPS stimulated monocyte-derived macrophages (MDMs) from Holstein (taurine) and Gir (indicine) breeds using RNA sequencing methodology. For unstimulated MDMs, the contrast between Holstein and Gir breeds identified 163 Differentially Expressed Genes (DEGs) highlighting the higher expression of C-C chemokine receptor type five (CCR5) and BOLA-DQ genes in Gir animals. LPS-stimulated MDMs from Gir and Holstein animals displayed 1,257 DEGs enriched for cell adhesion and inflammatory responses. Gir MDMs cells displayed a higher expression of M1 related genes like Nitric Oxide Synthase 2 (NOS2), Toll like receptor 4 (TLR4), Nuclear factor NF-kappa-B 2 (NFKB2) in addition to higher levels of transcripts for proinflammatory cytokines, chemokines, complement factors and the acute phase protein Serum Amyloid A (SAA). We also showed that gene expression of inflammatory M1 population markers, complement and SAA genes was higher in Gir in buffy coat peripheral cells in addition to nitric oxide concentration in MDMs supernatant and animal serum. Co-expression analyses revealed that Holstein and Gir animals showed different transcriptional signatures in the MDMs response to LPS that impact on cell cycle regulation, leukocyte migration and extracellular matrix organization biological processes. Overall, the results suggest that Gir animals show a natural propensity to generate a more pronounced M1 inflammatory response than Holstein, which might account for a faster immune response favouring resistance to many infection diseases.

Micrawave decomposition has been increasingly used hr a large number of samples. A method using an open vessel microwave was used for biological sample preparation with nitric acid vapors under atmospheric pressure. A lab made Teflon@ support suited with four cups, which received the samples, was inserted in the microwave vessel. These cups were used to weight 30 mg of certi5ed re5wence materials such as spinach and apple leaves, which received 150 pL of d.i. water to improve the micrawave e%ciency. This mixture was exposed to acid vapor stemmed from 15 mL of concentrated nitrie acid plsced in the bottom of the vessel hr decompoeition. The maximum microwave temperature, 115'C, was reached in 4 min. This condition was rnaintained hr 20 min to sllow complete decomposition of the sample. The deeomposed sample, in the cup, was diluted to 1.0 mL of d.i. water, shaken and centrifuged. The cups were than placed directed into an autosampler for Co and Fe analysis in an atomic absorption graphite fumace spectrometer. |
