Resident and Monocyte-Derived Macrophages in Cardiovascular Disease

Resident and Monocyte-Derived Macrophages in Cardiovascular Disease.

Macrophages are ubiquitous cells that reside in all major tissues. Counter to long-held beliefs, we now know that resident macrophages in many organs are seeded during embryonic development and self-renew independently from blood monocytes. Under inflammatory conditions, those tissue macrophages are joined and sometimes replaced by recruited monocyte-derived macrophages. Macrophage function in ...

Quantification and comparison of TLR2 activity in monocyte-derived macrophages of zebu and crossbred cattle

The present study was conducted to quantify and compare TLR2 (toll-like receptor 2) activity in monocyte-derived macrophages of zebu (Tharparkar) and crossbred (Holstein-Friesian × Jersey × Brown Swiss × Hariana) cattle. The cells were either induced with Pam3CSK4 or kept as control. The TLR2 activity was quantified in terms of IκB-α inhibitory subunit (NFKBIA) messenger RNA (mRNA) copies...

Oxidative metabolism in cord blood monocytes and monocyte-derived macrophages.

Little is known about phagocytosis-associated oxidative metabolism in mononuclear phagocytes from the human neonate. We investigated this phenomenon in monocytes from the cord blood of term newborn infants by measuring generation of superoxide anion (O2-) and hydroxyl radical (X OH) after stimulation with opsonized zymosan or phorbol myristate acetate. Production of these microbicidal oxygen me...
