Expression, purification and characterization of phosphatidylserine-targeting antibodies for biochemical and therapeutic applications.

Methods Cell Biol

January 2025

Department of Microbiology, Biochemistry and Molecular Genetics, (3)Center for Cell Signaling, Rutgers New Jersey Medical School, Newark, NJ, United States. Electronic address:

The externalization of Phosphatidylserine (PS) from the inner surface of the plasma membrane to the outer surface of the plasma membrane is an emblematic event during apoptosis and serves as a potent "eat-me" signal for the efferocytosis of apoptotic cells. Although less well understood, PS is also externalized on live cells in the tumor microenvironment and on live virus-infected cells whereby it serves as an immune modulatory signal that drives tolerance and immune escape. Given the importance of PS in cancer immunology and immune escape, PS-targeting monoclonal antibodies have been characterized with promising immunotherapeutic potential.

Electronic address:

Since cefixime and tellurite are known to inhibit most bacteria belonging to Enterobacterales, we found that addition of tellurite inhibited E. albertii growth in Luria Bertani broth but not in tryptic soy broth (TSB), and addition of phosphate and soy peptone enhanced E. albertii growth in TSB in presence of tellurite.

Objectives: Trunk control involves multiple brain regions related to motor control systems. Therefore, patients with central nervous system (CNS) disorders frequently exhibit impaired trunk control, decreasing their activities of daily living (ADL). Although some therapeutic interventions for trunk impairments have been effective, their general effects on CNS disorders remain unclear.

Aim: In the Japanese health checkup system for older adults aged ≥75 years, the Questionnaire for Medical Checkup of Old-Old (QMCOO) was adopted after 2020. However, the prognostic significance of this questionnaire for the incidence of functional disability is uncertain. The current study aimed to validate the prognostic significance of the QMCOO, and to develop a simple risk score for functional disability by analyzing health insurance claims data including annual health checkup data.

Aim: Despite the clinical importance and significant social burden of neuropsychiatric symptoms (NPS) in dementia, the underlying neurobiological mechanism remains poorly understood. Recently, neuroimaging-derived brain-age estimation by machine-learning analysis has shown promise as an individual-level biomarker. We investigated the relationship between NPS and brain-age in amnestic mild cognitive impairment (MCI) and early dementia.

Although the pathophysiology of idiosyncratic drug-induced liver injury (IDILI) is unclear, it is presumed to be immune-mediated, involving complex interactions between drug metabolism and activation of the immune system. The following four reactive metabolite production patterns are considered: (1) parent compounds into reactive metabolites within neutrophils or antigen-presenting cells (APCs), (2) reactive metabolites produced by cytochrome P450 (CYP), (3) nonreactive metabolites produced by CYP into reactive metabolites within APCs, and (4) reactive metabolites produced by non-CYPs. Reactive metabolites indirectly activate inflammasomes in APCs, leading to IDILIs.

Two reductases complete steroidal glycoalkaloids biosynthesis in potato.

New Phytol

January 2025

Graduate School of Agricultural Science, Kobe University, Rokkoudai 1-1, Nada, Kobe, Hyogo, 657-8501, Japan.

Steroidal glycoalkaloids (SGAs) are specialized metabolites primarily produced by Solanaceae plants such as potatoes and tomatoes. Notably, α-solanine and α-chaconine are recognized as toxic substances in potatoes. While the biosynthetic pathways of SGAs are largely understood, the final steps of α-solanine and α-chaconine biosynthesis remained elusive.

The influence of varying hydrogen content on the microstructure, mechanical properties, and fracture behavior of the metastable β titanium alloy TB8 after hydrogen charging has been investigated in this study. Several characterization methods, including optical microscopy (OM), x-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM), were employed to comprehensively analyze the alloy. The results show that with the addition of hydrogen, hydrogen mainly accumulated at grain boundaries in the form of hydrides.

Intercellular mitochondria transfer is an evolutionarily conserved process in which one cell delivers some of their mitochondria to another cell in the absence of cell division. This process has diverse functions depending on the cell types involved and physiological or disease context. Although mitochondria transfer was first shown to provide metabolic support to acceptor cells, recent studies have revealed diverse functions of mitochondria transfer, including, but not limited to, the maintenance of mitochondria quality of the donor cell and the regulation of tissue homeostasis and remodelling.

The judicious selection of ovulation inhibitors in ovarian stimulation protocols is crucial for the success of assisted reproductive technology (ART). Herein, we investigate the dose-dependent effects of chlormadinone acetate (CMA) and cetrorelix, two distinct ovulation inhibitors, on oocyte maturation in patients with normal ovarian reserve, using univariable and multivariable Poisson regression analyses. Patients undergoing progestin-primed ovarian stimulation (PPOS) with CMA (n = 299) or gonadotropin-releasing hormone antagonist (GnRH-ant) with cetrorelix (n = 605) during their initial in vitro fertilization cycle were enrolled at our center from March 2018 to October 2020 (N = 904).

The flagellar MS-ring is the initial template for flagellar assembly and houses the flagellar protein export complex. The MS-ring has three parts of different symmetries within the ring structure by assembly of FliF subunits in two different conformations with distinct arrangements of three ring-building motifs, RBM1, RBM2, and RBM3. However, it remains unknown how these symmetries are generated.
