nvolved in early stages of emotion processing during implicit regulation, while emerging adults recruit higher-order regions involved in the extraction of semantic meaning. Findings have implications for future research aiming to better understand the neurodevelopmental mechanisms underlying risk for psychopathology.

To investigate the feasibility and safety of haploidentical natural killer (NK) cell infusions as consolidation immunotherapy after autologous stem cell transplant (ASCT) in patients with plasma cell myeloma.

Ten patients (median age, 59 years) received induction treatment followed by high-dose melphalan (200 mg/m

) at day -1, ASCT at day 0 and increasing NK cell doses (1.5×10

, 1.5×10

and multiple doses of 1.0×10

cells/kg body weight) from day +1 to day +30 after ASCT. NK cells were harvested and purified from peripheral blood of haploidentical donors and expanded for 19 days with interleukin (IL)-2 and IL-15 under Good Manufacturing Practice conditions.

NK cell numbers increased 56.0-fold (37.4- to 75.5-fold). Patients received a median of 3.8×10

(0.9-5.7×10

) NK cells/kg body weight in six (three to eight) infusions. Multiparametric mass cytometry analysis demonstrated an altered surface receptor repertoire of expanded NK cells with increased degranulation and cytokine production activities but diminished expression of perforin. Donor NK cells were detectable in the peripheral blood, peaking 1 h after each dose (up to 90% donor NK cells). CCS-1477 The treatment was safe and well tolerated, without evidence of graft-versus-host disease. Comparison with a control patient population receiving ASCT without NK cell infusions showed no significant difference in relapse, progression-free survival and overall survival.

This study demonstrates reliable manufacturing of high numbers of activated NK cells for multiple-dose infusions and safe administration of these cellular products. The trial was registered at ClinicalTrials.gov (identifier no. NCT01040026).

Although the antioxidant mechanisms of ferroptosis have been extensively studied recently, little is known about the interactions between the different organelles that control ferroptosis. Here, we show that the translocation of lysosomal cysteine protease cathepsin B (CTSB) into the nucleus is an important molecular event that mediates organelle-specific initiation of ferroptosis in human pancreatic cancer cells. Iron-dependent lysosomal membrane permeability triggers the release of CTSB from the lysosome to nucleus during ferroptosis. Mechanistically, nuclear CTSB accumulation causes DNA damage and subsequent activation of the stimulator of interferon response CGAMP interactor 1 (STING1/STING)-dependent DNA sensor pathway, which ultimately leads to autophagy-dependent ferroptosis. Consequently, the genetic inhibition of CTSB-dependent STING1 activation by RNAi prevents ferroptosis in cell culture and animal models. These new findings not only enhance our understanding of the mechanism by which organelles specifically trigger ferroptosis, but also may provide a potential way to enhance the anticancer activity of ferroptosis therapy.Oxycodone is a common type of opioid used for the treatment of moderate to severe pain. Besides its analgesic effects on neuron cells, the effects of oxycodone on other cell types are yet to be elucidated. We previously demonstrated that oxycodone displayed both pro- and anti-cancer effects on bulk cancer cells. This work further investigated the effects of oxycodone on normal and malignant hematopoietic stem cells. Using hematopoietic CD34+ cells isolated from normal bone marrow (NBM) or patients with acute myeloid leukemia (AML), we showed that oxycodone activates hematopoietic cells regardless of cell development stage and malignant status. Oxycodone dose-dependently increases colony formation and self-renewal capacity of NBM and AML stem/progenitor cells, and promotes proliferation of AML bulk cells. NBM stem/progenitor cells are more sensitive to oxycodone than AML counterparts. In addition, oxycodone alleviates chemotherapy drug-induced toxicity in AML stem/progenitor cells. Mechanism studies demonstrate that oxycodone acts on hematopoietic cells in an opioid-receptor-independent manner. Oxycodone did not affect epithelial growth factor receptor (EGFR) signaling neither but stimulated Wnt/β-catenin signaling. Rescue studies via depleting β-catenin using genetic and pharmacological approaches confirmed that β-catenin was required for the activation of hematopoietic cells induced by oxycodone. Our work demonstrates 1) the protective role of oxycodone in malignant hematopoietic cells from chemotherapy; 2) stimulatory effects of oxycodone in normal hematopoietic stem cells; and 3) ability of oxycodone in Wnt signaling activation.

Total pancreatectomy with islet autotransplantation (TP-IAT) is an uncommon surgical procedure with unique perioperative management. We evaluated the short- and long-term morbidity and mortality of TP-IAT to optimize surgical technique and heparin dosing during islet autotransplantation.

Eighty patients with chronic pancreatitis undergoing TP-IAT were reviewed. Primary outcome was to evaluate morbidity and mortality based on operative technique classic (resection of antrum) vs pylorus-preserving. Secondary outcome was to evaluate the effect of heparin dosing (<60 vs≥60 units/kg) during islet autotransplantation on postoperative hemorrhage and portal vein thrombosis (PVT) rates.

There was no 90-day mortality, and median length of stay was 9 days. All patients underwent an open operation with 53 (66%) pylorus-preserving resections. The 30-day morbidity rate was 39%, with no difference between operative technique (p=0.82). The median dose was different for each heparin group (<60 52 units/kg vs≥60 66 units/kg, p<0.
