Erdheim-Chester Disease (ECD) is a rare form of histiocytosis characterized by xanthomatous infiltration of affected organs. We present a case of a 62-year-old man with ECD initially presenting with constrictive pericarditis. Comprehensive imaging revealed systemic involvement, including the skeleton, orbit, pituitary, lung, kidney, and retroperitoneum, despite the absence of related symptoms. The diagnosis of ECD was eventually confirmed through histopathological evidence from a CT-guided biopsy. The patient responded well to interferon-α2b treatment, with gradual symptom amelioration and improvement in imaging and laboratory findings over a 5-month follow-up period. This case highlights the importance of considering ECD in the differential diagnosis of constrictive pericarditis and the utility of multimodal imaging for accurate diagnosis and management of this rare disease. The patient\'s positive response to treatment also highlights the potential for effective management of ECD, particularly with early diagnosis and intervention.

Previous studies have shown that complexly shaped nanoparticles (NPs) have their intrinsic radiothermal emission in the millimeter range. This article presents a method for controlling the quality of nanodrugs-immunobiological preparations (IBPs)-based on the detection of their intrinsic radiothermal emissions. The emissivity of interferon (IFN) medicals, determined without opening the primary package, is as follows (µW/m2): IFN-α2b-80 ± 9 (105 IU per package), IFN-β1a-40 ± 5 (24 × 106 IU per package), IFN-γ-30 ± 4 (105 IU per package). The emissivity of virus-like particles (VLP), determined using vaccines Gam-VLP-multivac (120 μg) in an injection bottle (crimp cap vials), was as follows: 12 ± 1 µW/m2, Gam-VLP-rota vaccines-9 ± 1 µW/m2. This study shows the reproducibility of emissivity over the course of a year, subject to the storage conditions of the immunobiological products. It has been shown that accelerated aging and a longer shelf life are accompanied by the coagulation of active NPs, and lead to a manyfold drop in emissivity. The dependence of radiothermal emission on temperature has a complex, non-monotonic nature. The emission intensity depends on the form of dosage, but remains within the order of magnitude for IFN-α2b for intranasal aqueous solution, ointments, and suppositories. The possibility of the remote quantitative control of the first phases of the immune response (increased synthesis of IFNs) to the intranasal administration of VLP vaccines has been demonstrated in experimental animals.

UNASSIGNED: The exhaustion and poor homing of activated lymphocytes are critical obstacles in adoptive cell immunotherapy for solid tumors. In order to effectively deliver immune cells into tumors, we encapsulated interferon-α2b (IFN-α2b) into macroporous hydrogels as an enhancement factor and utilized low-dose irradiation (LDI) as a tumoral attractor of T cells.
UNASSIGNED: Hydroxypropyl cellulose hydrogels were prepared by irradiation techniques, and the cross-sectional microstructure was characterized by scanning electron microscopy. The synergistic antitumor mechanism of combination of IFN-α2b and CIK cells was evaluated by detecting the expression of activation marker CD69 on CIK cell surface and IFN-γ production by CIK cells. The in vivo antitumor activity of IFN-α2b-incorporated hydroxypropyl cellulose hydrogels combined with CIK and radiation was evaluated in an MKN-45 xenografted nude mice model.
UNASSIGNED: The bioactivity of IFN-α2b was well maintained in ultraviolet-reactive, rapidly cross-linkable hydroxypropyl cellulose hydrogels. In vitro studies demonstrated IFN-α2b-activated T cells, as evidenced by upregulating early activation marker CD69 and secretion inflammatory cytokine IFN-γ. In vivo real-time image showed our hydrogels kept a higher amount of drug delivery at the tumor site for a long time compared with free drug injection. Low-dose irradiation promoted T cell accumulation and infiltration in subcutaneous tumors. Combination of IFN-α2b-loaded hydrogels (Gel-IFN) with T cells and LDI exhibited higher efficacy to eradicate human gastric cancer xenograted tumors with less proliferating cells and more necrotic regions compared with IFN-α2b or T cells alone.
UNASSIGNED: HPC hydrogels kept the activity of IFN-α2b and stably release of IFN-α2b to stimulate T cells for a long time. At the same time, low-dose radiation recruits T cells into tumors. This innovative integration mode of IFN-α2b-loaded hydrogels and radiotherapy offers a potent strategy to improve the therapeutic outcome of T cell therapy.

Ocular surface squamous neoplasia is the most common tumour of the ocular surface. It is a spectrum of disease from intraepithelial dysplasia to invasive squamous cell carcinoma. Recent years have seen an increase in the use of topical chemotherapeutic agents to treat this condition, often as primary treatment without full-thickness biopsy. This practical approach provides a critical appraisal of the evidence base with the goal being to aid the clinician in the management of these patients.

We have developed an Escherichia coli strain for the in vivo production of O-glycosylated proteins. This was achieved using a dual plasmid approach: one encoding a therapeutic protein target, and a second encoding the enzymatic machinery required for O-glycosylation. The latter plasmid encodes human polypeptide N-acetylgalactosaminyl transferase as well as a β1,3-galactosyl transferase and UDP-Glc(NAc)-4-epimerase, both from Campylobacter jejuni, and a disulfide bond isomerase of bacterial or human origin. The effectiveness of this two-plasmid synthetic operon system has been tested on three proteins with therapeutic potential: the native and an engineered version of the naturally O-glycosylated human interferon α-2b, as well as human growth hormone with one engineered site of glycosylation. Having established proof of principle for the addition of the core-1 glycan onto proteins, we are now developing this system as a platform for producing and modifying human protein therapeutics with more complex O-glycan structures in E. coli.

Melanoma, is a highly aggressive and the most lethal form of skin cancer, and is known to be resistant to current therapeutic modalities. Interferon (IFN)-α2b is an immunostimulatory cytokine and is used to treat melanoma by inhibiting proliferation and promoting apoptosis of cells. However, there is a need to improve the efficacy of IFN-α2b. Inhibitor of growth family member 4 (ING4) has been reported to function as a tumor suppressor and is involved in regulating cell cycle progression, apoptosis, cell migration and invasion. Previously studies have also reported that caspase-3, caspase-8, poly (ADP-ribose) polymerase (PARP) and Fas/Fas ligand (FasL) pathways are involved in the process of apoptosis. In the present study, it was investigated whether overexpression of ING4 is able to enhance IFN-α2b response in human melanoma cells. It was determined that the overexpression of ING4 was able to increase the effects of IFN-α2b, and induce cell death and apoptosis in melanoma cells. Furthermore, the overexpression of ING4 resulted in decreased expression of PARP, caspase-3 and -8. The expression of cleaved PARP, cleaved caspase-3, cleaved caspase-8, Fas and FasL was increased in the A375 melanoma cell line. These results demonstrate that the overexpression of ING4 is able to enhance the anti-melanoma activity of IFN-α2b. These findings provide a potential therapeutic strategy where a combination of ING4 overexpression and IFN-α2b treatment may lead to higher levels of apoptosis in melanoma cells.

UNASSIGNED: Interferon (IFN)-α2b in Peyronie\'s disease (PD).
UNASSIGNED: This study aims to evaluate clinical efficacy of the IFN-α2b in both subjective and objective manner for the treatment of PD and compared with previously used intralesional verapamil in terms of cost-benefit analysis.
UNASSIGNED: Prospective study.
UNASSIGNED: A prospective study conducted from January 2013 to July 2016 in the Department of Urology, Government Medical College, Kota, Rajasthan, India. We included patients with identifiable Peyronie\'s plaque with or without pain, curvature ranging between 30 and 90 degrees. We excluded patients with a calcified plaque and the ventral location of the plaque, any infective foci over the penis, erectile dysfunction due to other etiologies and patients who had received previous intralesional therapy. Patients were evaluated by clinical history, physical examination including plaque location, size, consistency, and penile curvature. Patients received intralesional IFN-α2b in a dose of 3 × 106 IU. Patients completed the visual analogue pain (VAS) score for pain, and International Index of Erectile Function-5 (IIEF-5) questionnaire at first visit as well as at follow-up of 1 month and 3 months.
UNASSIGNED: Comparisons were performed using the paired Student\'s t-test and Chi-square tests as appropriate. Patient\'s objective and subjective clinical characteristics were described as a means (standard deviation).
UNASSIGNED: We included 86 patients in this study. Patients had a mean age of 48.6 years, mean plaque volume 256 mm3, and disease duration of 15.2 years. After 1 month of treatment, there was a significant change in plaque volume 256-60.8 mm3; P < 0.01) and penile curvature 34.8-24.6°; P < 0.01). The patients reported significant improvement in pain score VAS and IIEF-5.
UNASSIGNED: IFN-α2b, as minimal invasive (intralesional) options for the treatment of PD, demonstrated significant improvement in plaque volume, penile curvature with minimal complications. Patients subjectively reported significant improvement in pain on erection and sexual activities. IFN-α2b and verapamil had an almost similar clinical outcome, but verapamil at much lower cost.

BACKGROUND: Topical chemotherapy has gained popularity among clinicians for the treatment of ocular surface squamous neoplasia (OSSN). The principal topical chemotherapy agents used in the management of OSSN are interferon-α2b, 5-fluorouracil, and mitomycin C. High-resolution optical coherence tomography (HR-OCT) is a non-invasive technique that can differentiate OSSN from other ocular surface lesions.
UNASSIGNED: This review highlights the current regimens and diagnostic modalities used in managing OSSN. A review of the literature was performed using the keywords \"conjunctival intraepithelial neoplasia\", \"ocular surface squamous neoplasia\", \"optical coherence tomography\", \"interferon-α2b\", \"5-fluorouracil\" and \"mitomycin C\".
UNASSIGNED: Topical chemotherapy for OSSN can be used as primary therapy, for chemoreduction prior to surgical excision, and postoperatively to prevent tumor recurrence. It has the advantage of treating microscopic disease as well as large tumors. HR-OCT provides an \"optical biopsy\" that can assist in diagnosis and guide management of OSSN lesions.

Course treatment with IFN-α2b immobilized on polyethylene glycol stimulates phagocytic activity of peritoneal macrophages and neutrophils, enhances humoral immune response in CBA/CaLac mice, stimulates IL-4 synthesis, and suppresses IFN-γ production by mitogenstimulated splenocytes from experimental animals.

Legionaminic acids are analogs of sialic acid that occur in several bacteria. The most commonly occurring form is Leg5Ac7Ac, which differs from Neu5Ac only at the C7 (acetamido) and C9 (deoxy) positions. While these differences greatly reduce the susceptibility of Leg compounds to sialidases, several sialyltransferases have been identified that can use CMP-Leg5Ac7Ac as a donor (Watson et al. 2011). We report the successful modification with Leg5Ac7Ac of a glycolipid, GM1a, and two glycoproteins, interferon-α2b and α1-antitrypsin, by means of two mammalian sialyltransferases, namely porcine ST3Gal1 and human ST6Gal1. The Leg5Ac7Ac form of GD1a was not recognized by the myelin-associated glycoprotein (MAG, Siglec-4), confirming the importance of the glycerol moiety in the interaction of sialo-glycans with Siglecs.
