Recent Advances of Acute Kidney Injury in Hematopoietic Cell Transplantation.

Acute kidney injury (AKI) is a common complication of allogeneic hematopoietic cell transplantation (allo-HCT) and is associated with non-relapse mortality (NRM) and quality of life (QOL). Multiple factors may contribute to AKI during allo-HCT and are often present at the same time making it difficult to determine the cause of AKI in each patient. Nephrotoxic drugs, infections, thrombotic microangiopathy (TMA), and sinusoidal obstruction syndrome (SOS) are well described causes of AKI during allo-HCT. Acute graft-versus-host disease (aGVHD) is a major complication of allo-HCT that mainly targe

Ex vivo drug response heterogeneity reveals personalized therapeutic strategies for patients with multiple myeloma.

Multiple myeloma (MM) is a plasma cell malignancy defined by complex genetics and extensive patient heterogeneity. Despite a growing arsenal of approved therapies, MM remains incurable and in need of guidelines to identify effective personalized treatments. Here, we survey the ex vivo drug and immunotherapy sensitivities across 101 bone marrow samples from 70 patients with MM using multiplexed immunofluorescence, automated microscopy and deep-learning-based single-cell phenotyping. Combined with sample-matched genetics, proteotyping and cytokine profiling, we map the molecular regulatory netwo

Pilot Study: Human Adipose Tissue Allograft for Fat Pad Defects in Patients With Preulcerative Lesions.

BackgroundLoss or displacement of a fat pad on the foot increases plantar pressure, leading to pain and plantar ulcers. These ulcers, especially in patients with diabetic neuropathy, have high recurrence rates, often resulting in amputations. Standard of care focuses on reducing plantar pressure with shoe padding or orthotic devices, leaving the restoration of the fat pad as an unmet medical need. To address this, a human cryopreserved adipose tissue (hCAT) allograft has been developed to repair adipose tissue defects.MethodsScientific characterization of hCAT included assessments of its struc

Adaptive NK cells undergo a dynamic modulation in response to human cytomegalovirus and recruit T cells in in vitro migration assays.

Human cytomegalovirus (HCMV) reactivation remains a relevant complication after hematopoietic stem cell transplantation (HSCT) despite the great progress made in prophylaxis and treatment. Adaptive Natural Killer (NK) cells undergo a persistent reconfiguration in response to HCMV reactivation however, the exact role of adaptive NK cells in HCMV surveillance is currently unknown. We studied the relationship between HCMV reactivation and adaptive NK cells in 70 patients monitored weekly until day +100 after HSCT. Absolute cell counts of adaptive NK cells increased significantly after resolution

The osteogenic niche-targeted arsenic nanoparticles prevent colonization of disseminated breast tumor cells in the bone.

Up to 70% of patients with late-stage breast cancer have bone metastasis. Current treatment regimens for breast cancer bone metastasis are palliative with no therapeutic cure. Disseminated tumor cells (DTCs) colonize inside the osteogenic niches in the early stage of bone metastasis. Drug delivery into osteogenic niches to inhibit DTC colonization can prevent bone metastasis from entering its late stage and therefore cure bone metastasis. Here, we constructed a 50% DSS6 peptide conjugated nanoparticle to target the osteogenic niche. The osteogenic niche was always located at the endosteum with

IDH Mutations in Glioma: Molecular, Cellular, Diagnostic, and Clinical Implications.

In 2021, the World Health Organization classified isocitrate dehydrogenase (IDH) mutant gliomas as a distinct subgroup of tumors with genetic changes sufficient to enable a complete diagnosis. Patients with an IDH mutant glioma have improved survival which has been further enhanced by the advent of targeted therapies. IDH enzymes contribute to cellular metabolism, and mutations to specific catalytic residues result in the neomorphic production of D-2-hydroxyglutarate (D-2-HG). The accumulation of D-2-HG results in epigenetic alterations, oncogenesis and impacts the tumor microenvironment via i

MGluR5 Agonist, CHPG, увеличивает число дифференцированных человеческих олигодендроцитов.

Предыдущие исследования на взрослых мышах показывают, что 2-хлор-5-гидроксифениловый гликин (CHPG) MGluR5 сокращает потери в миелине, вызванные купризоной. Этот эффект частично привязывается CHPG к рецепторам mGluR5 для реактивных астроцитов, что приводит к высвобождению нервно-партрофного фактора мозга (BDNF), что приводит к увеличению миелина и уменьшает поведенческий дефицит. Однако остается неясным, оказывает ли CHPG аналогичное благотворное воздействие на клетки человека. Для решения этой проблемы мы изучили воздействие CHPG на клетки человека, используя как индуцированные плюрипотентными

CD28 Deficiency Ameliorates Blast Exposure-Induced Lung Inflammation, Oxidative Stress, Apoptosis, and T Cell Accumulation in the Lungs via the PI3K/Akt/FoxO1 Signaling Pathway.

Although CD28 is associated with the expression of inflammatory mediators, apoptosis-related protein, immunosuppression, and tumorigenesis, the effects of CD28 deficiency on blast exposure-induced lung injury have not been investigated. In this study, we have explored the effects of CD28 on blast exposure-induced lung injury and studied its potential molecular mechanisms. A mouse model of blast exposure-induced acute lung injury was established. Sixty C57BL/6 wild-type (WT) and CD28 knockout (CD28-/-) mice were randomly divided into control or model groups.

A new era in the management of spinal metastasis.

Despite the recent advances in cancer treatment, the incidence of patients with spinal metastases continues to grow along with the total number of cancer patients. Spinal metastases can significantly impair activities of daily living (ADL) and quality of life (QOL), compared with other types of bone metastases, as they are characterized with severe pain and paralysis caused by skeletal-related events. Reduced ADL can also lead to treatment limitations as certain anticancer agents and radiation therapy are not compatible treatments; thus, leading to a shorter life expectancy. Consequently, main

Bortezomib alters sour taste sensitivity in mice.

Chemotherapy-induced taste disorder is one of the critical issues in cancer therapy. Bortezomib, a proteasome inhibitor, is a key agent in multiple myeloma therapy, but it induces a taste disorder. In this study, we investigated the characteristics of bortezomib-induced taste disorder and the underlying mechanism in mice. Among the five basic tastes, the sour taste sensitivity of mice was significantly increased by bortezomib administration. In bortezomib-administered mice, protein expression of PKD2L1 was increased. The increased sour taste sensitivity induced by bortezomib returned to the co

Конвергенция генетики вируса хост и Эпштейн-Барр в множестве склерозов.

Недавние сероэпидемиологические исследования укрепили гипотезу о том, что вирус Эпштейн-Барр (ЭБВ) может быть причиной множественного склероза (МС). С учетом сложности взаимодействия EBV-принимателя различные механизмы могут нести ответственность за патогенез болезни. Кроме того, остается неясным, относится ли это к конкретным заболеваниям. Здесь мы показали, что гены, кодирующие взаимодействие EBV, обогащаются в лоси, связанных с MS, но не с другими заболеваниями и в приоритетных терапевтических целях. Анализ крови MS и транскриптомов мозга подтвердил дисрегулирование связанных с MS EBV интер

Oncofetal Chondroitin Sulfate Is a Highly Expressed Therapeutic Target in Non-Small Cell Lung Cancer.

Broad-spectrum therapeutics in non-small cell lung cancer (NSCLC) are in demand. Most human solid tumors express proteoglycans modified with distinct oncofetal chondroitin sulfate (CS) chains that can be detected and targeted with recombinant VAR2CSA (rVAR2) proteins and rVAR2-derived therapeutics. Here, we investigated expression and targetability of oncofetal CS expression in human NSCLC. High oncofetal CS expression is associated with shorter disease-free survival and poor overall survival of clinically annotated stage I and II NSCLC patients (n = 493). Oncofetal CS qualifies as an independ
