Human genetics, biomarker, and animal studies implicate loss of function in bone morphogenetic protein (BMP) signaling maladaptive transforming growth factor-β (TGFβ) as drivers pulmonary arterial hypertension (PAH). Although sharing common receptors effectors with BMP/TGFβ, the activin differentiation factor (GDF) ligands PAH are less well defined. Increased expression GDF8, GDF11, A was detected lung lesions from humans experimental rodent models (PH). ACTRIIA-Fc, a potent GDF8/11 ligand...
Rationale: BMP9 (bone morphogenetic protein 9) is a circulating endothelial quiescence factor with protective effects in pulmonary arterial hypertension (PAH). Loss-of-function mutations BMP9, its receptors, and downstream effectors have been reported heritable PAH.Objectives: To determine how an acquired deficiency of signaling might contribute to PAH.Methods: Plasma levels antagonist soluble endoglin were measured group 1 PAH, 2 3 (PH), patients severe liver disease without...
Abstract The osteoblast differentiation capacity of skeletal stem cells (SSCs) must be tightly regulated, as inadequate bone formation results in low mass and fragility, over-exuberant osteogenesis heterotopic ossification (HO) soft tissues. RUNX2 is essential for tuning this balance, but the mechanisms posttranslational control remain to fully elucidated. Here, we identify that a CK2/HAUSP pathway key regulator stability, Casein kinase 2 (CK2) phosphorylates RUNX2, recruiting deubiquitinase...
Immune checkpoint blockade (ICB) enhances T cell responses against cancer, leading to long-term survival in a fraction of patients. CD8 + differentiation response chronic antigen stimulation is highly complex, and it remains unclear precisely which states at anatomic sites are critical for the ICB. We identified an intermediate-exhausted population white pulp spleen that underwent substantial expansion ICB gave rise tumor-infiltrating clonotypes. Increased systemic redirected this toward...
<h3>Background</h3> CD8<sup>+</sup> T cell fate decision refers to the differentiation of a naïve into effector, memory, exhausted, or other fates. Evidence from chronic infection and cancer models suggest that signals during priming are especially important in determining thus functional quality response.<sup>1–4</sup> Priming interactions highly complex, requiring integration multiple signals, each which varies strength duration. Thus, we currently do not comprehend combinatorial...

Introduction: Therapies targeting the underlying mechanisms of pulmonary arterial hypertension (PAH) might modify natural history disease. The genetics heritable PAH implicate deficient BMP signaling as a pathogenetic driver. Lung tissues from experimental and human exhibit & excessive TGFβ signaling. While previous studies suggest agonism BMP9 or inhibition may prevent PH, roles activin growth differentiation factor (GDF) ligand are unclear. ACTRIIA-Fc (sotatercept) is an activin-...
