Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus type-2 (SARS-CoV-2), has quickly become a global pandemic. Most multiple sclerosis (MS) patients use disease-modifying treatments (DMTs), such as immunomodulators or immunosuppressants. By targeting different types of immune cells, DMTs affect cellular and/or humoral immunity. The potential effects of DMTs on the long-term immune response to COVID-19 is not fully known. Between 16.04.2020 and 15.07.2020, a total of 34 people, 17 of whom were diagnosed with MS according to the 2010 McDonald diagnostic criteria and a control group of 17 individuals who did not have a known systemic disease who were matched according to age, gender, and COVID-19 disease severity, where all received COVID-19 diagnosis with SARS-CoV-2 PCR positivity in nasopharyngeal swab test and immune responses were measured (SARS-CoV-2 IgM and IgG antibody levels COVID 19 ELISA kit), were included in our study. Demographic data of MS patients and the control group, SARS-CoV-2 immune responses, antibody titers and disease year of MS patients, EDSS scores, disease type, and disease duration were determined. All patients were symptomatic for COVID-19. COVID-19 disease severity was divided into three groups as mild, moderate, and severe according to the clinical condition of the patient. Demographic data of MS patients and the control group, SARS-CoV-2 immune responses, antibody titers and disease year of MS patients, EDSS scores, disease type, and disease duration were determined. All patients were symptomatic for COVID-19. COVID-19 disease severity was divided into three groups as mild, moderate, and severe according to the clinical condition of the patient. According to our study results, IgG-type long-term immune responses were lower in MS patients using DMTs than in the healthy population. We hope that our study will provide insight into the COVID-19 vaccine immune responses.

Acute pancreatitis (AP) is a disease characterized by an acute inflammatory response in the pancreas. This is caused by the abnormal activation of pancreatic enzymes by a variety of etiologic factors, which results in a localized inflammatory response. The symptoms of this disease include abdominal pain, nausea and vomiting and fever.

Recent advances in oncology research have highlighted the promising synergy between low-dose radiation therapy (LDRT) and immunotherapies, with growing evidence highlighting the unique benefits of the combination. LDRT has emerged as a potent tool for stimulating the immune system, triggering systemic antitumor effects by remodeling the tumor microenvironment. Notably, LDRT demonstrates remarkable efficacy even in challenging metastatic sites such as the liver (uveal) and brain (cutaneous), particularly in advanced melanoma stages.

Background: The rapid mutation of avian influenza virus (AIV) poses a significant threat to both the poultry industry and public health. Herein, we have successfully developed an mRNA-LNPs candidate vaccine for H5 subtype highly pathogenic avian influenza and evaluated its immunogenicity and protective efficacy.
Results: In experiments on BALB/c mice, the vaccine candidate elicited strong humoral and a certain cellular immune responses and protected mice from the heterologous AIV challenge.

Excessive vascularization during tracheal in-stent restenosis (TISR) is a significant but frequently overlooked issue. We developed an anti-inflammatory coupled anti-angiogenic airway stent (PAGL) incorporating anlotinib hydrochloride and silver nanoparticles using advanced electrospinning technology. PAGL exhibited hydrophobic surface properties, exceptional mechanical strength, and appropriate drug-release kinetics.

Background: Enterovirus 71 (EV71) is one of the major causative agents of hand, foot, and mouth disease (HFMD), and can cause severe cerebral complications and even fatality in children younger than 5 years old. However, there is no specific medication for EV71 infection in clinical practice. Our previous studies had identified the 6-thioguanine (6-TG), an FDA-approved anticancer drug, as a potential antiviral agent, but its anti-EV71 activity is largely unknown, therefore, we aim to explore the antiviral effect of 6-TG on EV71.
