Here, we have studied the role of eDNA in mixed-species microcolony formation in co-culture biofilms. Our study emphasizes the importance of eDNA as a common biofilm EPS component. In summary, we have shown that eDNA behaves as an essential EPS material shared by different species in co-culture biofilms, which facilitates interspecies interactions through the formation of mixed-species compact microcolony structures during biofilm development. Further understanding of mixed-species biofilm formation may provide valuable information

for the diagnostics and therapeutics of biofilm-related problems in medical and industrial environments.

“Little is known about postpartum immune recovery and relationships of common PtdIns(3,4)P2 dysphoric moods, stress, immunology, and endocrinology. Healthy women (n = 72) were followed for six postpartum months with immune and hormone measures and dysphoric moods and stress scales. A panel of cytokines produced in mitogen-stimulated whole blood assays were measured at each time, along with plasma levels of hsC-reactive protein (hsCRP), Interleukin-6 (IL-6), and a panel of hormones. Cellular immunity, measured by production of Interferon-gamma (IFNγ) and (Interleukin-2 (IL-2) from stimulated whole blood

culture, was low in the early postpartum with changes by 3 months. Tumor necrosis factor alpha (TNFα) showed a similar pattern. Plasma levels of CRP and Interleukin-6 (IL-6) showed higher levels in the early postpartum. Mood disturbance scores dropped across the postpartum with a change in slope at 3 months. No significant relationships were found between immune, endocrine, and psychosocial measures. Return to normal cellular immune function may take 3–4 months in the postpartum. Some aspects of early immunology (hsCRP and IL-6) probably reflect the latter stage of pregnancy, the stress of birth and the inflammation associated with involution. Dysphoric moods are higher in the early postpartum but are not related to immune factors or hormones. “
“We have previously shown that in differentiated T-helper (Th)1 and Th2 cells, polycomb group (PcG) proteins are associated differentially with the promoters of the signature cytokine genes.
