Incidence of thrombosis in relapsed/refractory B-cell lymphoma treated with axicabtagene ciloleucel: Mayo Clinic experience

Chimeric antigen receptor (CAR) T-cell therapy is effective in relapsed/refractory large B-cell lymphoma and results in a unique toxicity profile, namely cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome. The hyper-inflammatory state associated with these toxicities has been suggested to increase the risk of thrombosis.
We conducted a retrospective analysis of patients treated with axicabtagene ciloleucel (axi-cel) to assess the rate of thrombosis with axi-cel therapy from the time of CAR T-cell infusion until the end of hospitalization, when performed in the inpatient setting, or up to day +30 when performed in the outpatient setting. Ninety-two (95%) of 97 patients were hospitalized during axi-cel therapy and 85 (88%) developed CRS. Fifty-five patients (57%) received concurrent anticoagulation (53 as prophylaxis). Patients with prior VTE did not have progression https://joplink.net/antigens/ or evidence of new VTE. Only 2 (2.1%) patients developed VTE. These results demonstrate a low-risk for thrombosis in axi-cel recipients.

The Protective Action of Piperlongumine Against Mycobacterial Pulmonary Tuberculosis in Its Mitigation of Inflammation and Macrophage Infiltration in Male BALB/c Mice

Introduction: Piperlongumine (PL) is a bioactive alkaloid and medicinal compound of piperamide isolated from the long pepper (Piper longum Linn). It has demonstrated bactericidal action against Mycobacterium tuberculosis (MTB), the cause of pulmonary tuberculosis; nevertheless, immunomodulatory activity had not been identified for it in MTB-triggered granulomatous inflammation. This study investigated if piperlongumine could inhibit such inflammation.
Material and methods: Mycobacterium tuberculosis strain H37Rv was subjected to a broth microdilution assay. Piperlongumine at 5, 15, and 25 μg/mL, 0.2% dimethyl sulphoxide as control or 4 μM of dexamethasone were tested in vitro on MH-S murine alveolar macrophages. BALB/c mice were orally administered PL at 50, 100 and 150 mg/kg b.w. after trehalose-6,6-dimycolate (TDM) stimulation.
Chemokine and cytokine concentrations were determined in lung supernatants. Flow cytometry and Western blot analysis were performed to determine phosphorylated spleen tyrosine kinase (Syk), c-Jun N-terminal kinase (JNK) and extracellular signal-regulated kinase (ERK) pathways.
Results: Piperlongumine inhibited inflammatory mediators and adherence of lymphocyte function-associated antigen 1 to MH-S cells following TDM activation. It also improved macrophage clearance of MTB. In TDM-stimulated MH-S cells, PL significantly influenced the macrophage inducible Ca2+-dependent lectin receptor (Mincle)-Syk-ERK signalling pathway. Oral dosing of PL effectively suppressed the development of pulmonary granulomas and inflammatory reactions in the TDM-elicited mouse granuloma model.

Prevalence of Toxoplasma Gondii in Retail Fresh Meat Products from Free-range Chickens in Spain

Toxoplasma gondii is one of the most prevalent zoonotic protozoan parasites worldwide and affects the vast majority of warm-blooded animal species, including humans. Postnatal infection in humans occurs through the ingestion of sporulated T. gondii oocysts or via the oral intake of parasite tissue cysts during the consumption of raw or undercooked meat. In this regard, given their high exposure to oocysts, chickens (Gallus domesticus) raised on the ground constitute a potential source of T. gondii.
Material and methods: For the first time in Spain, a survey was undertaken in commercial retail free-range poultry. A total of 50 thighs from different animals were analysed. The samples were homogenised and an acid pepsin digestion procedure was applied prior to molecular analysis. Toxoplasma gondii DNA was isolated from meat by qPCR. Two sets of primers were used for DNA amplification targeting the specific sequence of a 529 bp repeat element and another set of primers was utilised for the surface antigen protein-1 gene.

Interrelationships between amphiregulin, kisspeptin, FSH and FSH receptor in promotion of human ovarian cell functions

The aim of this study was to investigate: (1) the ability of granulosa cells to produce amphiregulin (AREG), kisspeptin (KISS) and FSH receptor (FSHR); (2) the role of AREG and KISS in the control of ovarian functions; (3) the effect of FSH and KISS on AREG; and (4) the ability of KISS to affect FSHR and to modify FSH action on AREG output by human ovarian granulosa cells. We examined: (1) time-dependent accumulation of AREG; (2) effects of AREG (0, 1, 10, 100ng/mL) and KISS (0, 1, 10, 100ng/mL) on granulosa cell functions; and (3) the effects of KISS (0, 1, 10, 100ng/mL), FSH (0, 1, 10, 100ng/mL), and their combinations on AREG release.
Viability, markers of proliferation [accumulation ofproliferating cell nuclear antigen (PCNA) cyclin B1 and sodium 3′-[1-(phenylaminocarbonyl)-3,4-tetrazolium]-bis(4-methoxy6-nitro)benzene sulfonic acid hydrate (XTT formazan)] and apoptosis (accumulation of bax, caspase 3 and terminal deoxynucleotidyl transferase dUTP nick-end labelling), accumulation of KISS, FSHR and steroid hormones, and AREG release were analysed by Trypan blue exclusion test, quantitative immunocytochemistry, XTT, terminal deoxynucleotidyl transferase dUTP nick-end labelling assays and enzyme-linked immunosorbent assay.
AREG promoted cell viability, proliferation and steroid hormone output, and inhibited apoptosis. KISS (1 and 10ng/mL) stimulated viability, proliferation, steroid hormone release and occurrence of FSHR and suppressed apoptosis and AREG output; KISS (100ng/mL) had the opposite effect. FSH stimulated AREG release, whilst addition of KISS reversed this FSH effect. FSH mimicked and promoted the inhibitory effect of KISS on AREG release. These results suggest an intra-ovarian production and a functional interrelationship between AREG, KISS, FSH and FSHR in direct regulation of basic ovarian cell functions.

Novel PE and APC tandems: Additional near-infrared fluorochromes for use in spectral flow cytometry

Recent advances in flow cytometry instrumentation and fluorochrome chemistries have greatly increased fluorescent conjugated antibody combinations that can be used reliably and easily in routine experiments. The Cytek Aurora flow cytometer was first released with three excitation lasers (405, 488, and 640 nm) and incorporated the latest Avalanche Photodiode (APD) technology, demonstrating significant improvement in sensitivity for fluorescent emission signals longer than 800 nm.
However, there are limited commercially available fluorochromes capable of excitation with peak emission signals beyond 800 nm. To address this gap, we engineered six new fluorochromes: PE-750, PE-800, PE-830 for the 488 nm laser and APC-750, APC-800, APC-830 for the 640 nm laser.
Utilizing the principal of fluorescence resonance energy transfer (FRET), these novel structures were created by covalently linking a protein donor dye with an organic small molecule acceptor dye. Additionally, each of these fluorochrome conjugates were shown to be compatible with fixation/permeabilization buffer reagents, and demonstrated acceptable brightness and stability when conjugated to antigen-specific monoclonal antibodies. These six novel fluorochrome reagents can increase the numbers of fluorochromes that can be used on a spectral flow cytometer.

Paraneoplastic and Other Autoimmune Encephalitides: Antineuronal Antibodies, T Lymphocytes, and Questions of Pathogenesis

Autoimmune and paraneoplastic encephalitides represent an increasingly recognized cause of devastating human illness as well as an emerging area of neurological injury associated with immune checkpoint inhibitors. Two groups of antibodies have been detected in affected patients. Antibodies in the first group are directed against neuronal cell surface membrane proteins and are exemplified by antibodies directed against the N-methyl-D-aspartate receptor (anti-NMDAR), found in patients with autoimmune encephalitis, and antibodies directed against the leucine-rich glioma-inactivated 1 protein (anti-LGI1), associated with faciobrachial dystonic seizures and limbic encephalitis. Antibodies in this group produce non-lethal neuronal dysfunction, and their associated conditions often respond to treatment.
  • Antibodies in the second group, as exemplified by anti-Yo antibody, found in patients with rapidly progressive cerebellar syndrome, and anti-Hu antibody, associated with encephalomyelitis, react with intracellular neuronal antigens.
  • These antibodies are characteristically found in patients with underlying malignancy, and neurological impairment is the result of neuronal death. Within the last few years, major advances have been made in understanding the pathogenesis of neurological disorders associated with antibodies against neuronal cell surface antigens.
  • In contrast, the events that lead to neuronal death in conditions associated with antibodies directed against intracellular antigens, such as anti-Yo and anti-Hu, remain poorly understood, and the respective roles of antibodies and T lymphocytes in causing neuronal injury have not been defined in an animal model.
  • In this review, we discuss current knowledge of these two groups of antibodies in terms of their discovery, how they arise, the interaction of both types of antibodies with their molecular targets, and the attempts that have been made to reproduce human neuronal injury in tissue culture models and experimental animals.
  • We then discuss the emerging area of autoimmune neuronal injury associated with immune checkpoint inhibitors and the implications of current research for the treatment of affected patients.

 

Cultivated oral mucosal epithelial transplantation for persistent epithelial defect in severe ocular surface diseases with acute inflammatory activity.

OBJECTIVE
To assess the medical efficacy of cultivated oral mucosal epithelial transplantation (COMET) for the remedy of persistent epithelial defect (PED).
METHODS
We handled 10 eyes of 9 sufferers with PED (Stevens-Johnson syndrome: three eyes; thermal/chemical harm: 5 eyes; ocular cicatricial pemphigoid: two eyes) with COMET at Kyoto Prefectural University of Medicine, Kyoto, Japan from 2002 to 2008.
RESULTS
Preoperatively, PED existed on over greater than 50% of the corneal surface in seven eyes. Severe ocular surface irritation with fibrovascular tissue surrounded the PED in all 10 eyes. At 24-weeks postoperative, PED had improved in all instances besides 1 in which the affected person was unable to return to the hospital (95% CI, 55.5-99.7; Wilcoxon signed-rank check, p = 0.0078).
The preoperative median of logarithmic minimal angle of decision was 1.85 (vary 0.15-2.70), and 1.85, 1.85, and 1.52 on the 4th, 12th, and 24th postoperative week, respectively.
The imply whole preoperative ocular surface grading rating was 7.0 (vary 4-17). At Four and 12 weeks postoperative, the whole ocular surface grading rating had improved considerably (p = 0.0020, p = 0.0078), and at 24 weeks postoperative, it was 3.0 (vary 2-12, p = 0.0234). During the follow-up interval (median 23.Three months, vary 5.6-39.7 months), no recurrence of PED was noticed in any eye, and long-term ocular surface stability was obtained.
CONCLUSIONS
COMET enabled full epithelialization of PED and stabilization of the ocular surface in sufferers with severe ocular surface illness, thus stopping end-stage cicatrization and imaginative and prescient loss at a later stage.
