Varicella-Zoster Virus Infection and Varicella-Zoster Virus Vaccine-Related Ocular Complications.

The varicella-zoster virus is a human herpesvirus that causes varicella as the primary infection and HZ as the reactivation of a latent infection. Ten to twenty percent of cases of herpes zoster ophthalmicus (HZO) involve the ophthalmic branch of the fifth cranial nerve. Any area of the eye may be affected by the condition. HZ has a lifetime risk of more than 30%. Complications from herpes zoster can significantly lower quality of life. The goal of HZ vaccinations is to stop HZ activation and PHN formation. Despite the uncommon possibility of side effects such as eye problems, the majority of

A novel NKG2A alpaca nanobody targeting immune checkpoint blockade for the treatment of malignant melanoma.

Alpacas belong to the Camelidae family. Antibodies produced through alpaca immunization are called nanoantibodies. Compared to traditional antibodies, nanoantibodies have several characteristics, including smaller molecular weight, stable structure, high homology with human antibodies, and suitability for prokaryotic expression. Malignant melanoma (MM) is a severe and aggressive form of cancer that affects both humans and animals. It commonly arises in the mucous membranes of the skin, nose, mouth, anus, and digestive tract, as well as in the choroid of the eyes. Multiple factors contribute to

A review of feline infectious peritonitis virus infection.

Feline infectious peritonitis (FIP) is an infectious disease characterized by non-specific laboratory changes and clinical signs. Clinical symptoms include anorexia, jaundice, fever, and weight loss. Moreover, some lesions are found in the digestive and respiratory systems. FIP, whose virulence varies, cannot be distinguished using several diagnostic methods. Moreover, feline coronaviruses (FCoVs) can be classified into two serotypes based on differences in their amino acid sequences, spike (S) protein sequences, and antibody (Ab) neutralization. There are two pathotypes, namely those caused b

Multidisciplinary Management of Morbidities Associated with Chronic Graft-Versus-Host Disease.

Chronic graft-versus-host disease (cGVHD) represents a common long-term complication after allogeneic hematopoietic stem cell transplantation (HSCT). It imposes a significant morbidity burden and is the leading cause of non-relapse mortality among long-term HSCT survivors. cGVHD can manifest in nearly any organ, severely affecting the quality of life of a transplant survivor. While the mainstay of treatment has remained systemic immunosuppression with glucocorticoids, progress has been made within the last few years with approvals of three oral agents to treat steroid-refractory cGVHD: ibrutin

Ocular toxicities associated with anticancer drug therapy in Asian patients: a literature review and practical management recommendations for non-ophthalmologic settings.

BACKGROUND: Ocular toxicities associated with anticancer therapies, including cytotoxic chemotherapy, hormonal agents, molecular targeted therapies, immune checkpoint inhibitors, and antibody-drug conjugates, are increasingly recognized and may substantially impair visual function and quality of life. However, ethnicity-specific data for Asian populations and practical management strategies applicable to non-ophthalmologic settings remain limited. METHODS: A literature review of publications up to December 2025 was conducted using PubMed to identify studies reporting incidence, mechanisms, pr

Burden, Outcome, and Comorbidities of Extrahepatic Manifestations in Hepatitis B Virus Infections.

Hepatitis B virus (HBV) infections affect approximately 296 million people around the world, and the prevalence of any past or present HBV infection during the years 2015-2018 was as high as 4.3%. Acute HBV infection often presents with nonspecific symptoms and is usually self-limited, but 5% of patients can have persistent infections leading to chronic HBV infection and the risk of turning into chronic HBV infection is significantly higher in babies with vertical transmission (95%). Patients with chronic HBV infection are usually asymptomatic, but 15 to 40% of chronic HBV carriers develop cir

Feline infectious peritonitis.

The article discusses feline infectious peritonitis (FIP), an important disease frequently seen in veterinary practice. FIP causes many problems to the veterinarian as it can be difficult to definitively diagnose the disease, as there is no effective treatment, and as prophylactic interventions are not very successful. Although intense research has created a lot of new knowledge about this disease in the last years, there are still many unanswered questions. The objective of this article is to review recent knowledge and to increase understanding of the complex pathogenesis of FIP.

Antibiotic-Free Gene Vectors: A 25-Year Journey to Clinical Trials.

Until very recently, the major use, for gene therapy, specifically of linear or circular DNA, such as plasmids, was as ancillary products for viral vectors' production or as a genetic template for mRNA production. Thanks to targeted and more efficient physical or chemical delivery techniques and to the refinement of their structure, non-viral plasmid DNA are now under intensive consideration as pharmaceutical drugs. Plasmids traditionally carry an antibiotic resistance gene for providing the selection pressure necessary for maintenance in a bacterial host. Nearly a dozen different antibiotic-f

Изучение точных методов лечения иммунизированных подстрекательских заболеваний: использование бесконечного потенциала доставки нуклеиновой кислоты.

Неизлечимые подстрекательские заболевания (ИМИД) создают неизмеримое бремя для отдельных лиц и общества. В то время как традиционное использование иммунодепрессантов и лекарственных средств для борьбы с заболеваниями обеспечивает частичную помощь и контроль, их неизбежные побочные эффекты и ограниченная эффективность ставят под сомнение возможность найти лекарство. Перспективные лекарства от нуклеиновой кислоты продемонстрировали способность оказывать точное воздействие на молекулярном уровне, при этом различные классы нуклеиновых кислот выполняют регулирующие функции с помощью различных механ

Bispecific antibodies: unleashing a new era in oncology treatment.

Advancements in diagnostic and therapeutic standards have substantially enhanced the survival of patients with malignant tumors. Nevertheless, the quest for effective strategies to address resistant or recurrent advanced tumors remains a critical and unwavering objective. Bispecific antibodies (BsAbs) unleashed a new era of anti-tumor treatment by simultaneously binding to two distinct targets, thereby enhancing specificity, minimizing off-target toxicities, and synergistically modulating anti-tumor immunity and the tumor microenvironment. Compared with the combination of two monoclonal antibo

In vitro расширила человека CD4+CD25+ регуляционные T клетки, подавляющие распространение Т клеток.

Регулирующие Т клетки (Tregs) оказались критически важными в балансе между автоиммунизацией и терпимостью и были связаны с несколькими аутоиммунными заболеваниями человека. Однако небольшое число трегов в периферии крови ограничивает их терапевтический потенциал. Поэтому мы разработали протокол, который позволит расширить "Трегз" при сохранении их подавляющей активности. Мы изолировали клетки CD4+CD25 hi от человеческой периферической крови и расширили их in vitro в присутствии anti-CD3 и anti-CD28 Магнитные кситы и высокие концентрации внешнего интерлейкина (IL) -2.
