A Potent Myeloid Response Is Rapidly Activated in the Lungs of Premature Rhesus Macaques Exposed to Intra-Uterine Inflammation

Up to 40% of preterm births are associated with histological chorioamnionitis (HCA), which can lead to neonatal mortality, sepsis, respiratory disease, and neurodevelopmental problem. Researchers used rhesus macaques to comprehensively describe HCA-induced fetal mucosal immune responses and delineate the individual roles of IL-1β and TNFα in HCA-induced fetal pathology. Their data indicate that the fetal innate immune system can mount a rapid, multifaceted pulmonary immune response to in utero exposure to inflammation. Taken together, this work provides mechanistic insights into the association between HCA and the postnatal lung morbidities of the premature infant and highlights the therapeutic potential of inflammatory blockade in the fetus.

Complement Blockade in Recipients Prevents Delayed Graft Function and Delays Antibody-mediated Rejection in a Nonhuman Primate Model of Kidney Transplantation
Eerhart et al., Transplantation. 2022.
Investigators evaluated the efficacy of a high-dose recombinant human C1 esterase inhibitor (rhC1INH) in preventing delayed graft function (DGF) in a rhesus macaque (RM) model for kidney transplantation after brain death and prolonged cold ischemia. The majority (4 of 5) of vehicle-treated recipients developed DGF, whereas DGF was observed in only 1 of 8 rhC1INH-treated recipients. RMs treated with rhC1INH also had faster creatine recovery, superior urinary output, and reduced biomarkers of allograft injury for the first week. The results suggest high-dose C1INH treatment in transplant recipients is an effective strategy to reduce kidney injury and inflammation, prevent DGF, delay antibody-mediated rejection development, and improve transplant outcomes.
