Five Babesia bovis recombinant proteins, including merozoite surface antigen 2c (BbMSA-2c), C-terminal rhoptry-associated protein 1 (BbRAP-1/CT), truncated thrombospondin-related anonymous protein (BbTRAP-T), spherical body protein 1 (BbSBP-1), and spherical body protein 4 (BbSBP-4), were evaluated as diagnostic antigens to detect the infection in cattle. The recombinant proteins were highly an...

Hepatitis B virus (HBV) is an etiological agent of hepatitis B infection. Hepatitis B is a life-threatening disease that affects the liver. The clinical outcomes of the disease are varied from asymptomatic disease to serious complication such as cirrhosis and hepatocellular carcinoma (HCC). Despite availability of the vaccine and appropriate treatment, hepatitis B infection still remains a majo...

        Ricin, the toxic lectin extracted from the castor bean plant (Ricinus communis), consists of an A chain (RTA) and a B chain (RTB). Anti-A chain Abs and anti-B chain Abs can neutralize toxins in vivo and in vitro via blocking the binding of the toxin to the cell. Also, RTB protein is able to serve as an antigen deliver to the mucosal immune system and act as an immunoad...

INTRODUCTION Hepatitis B vaccination starting at birth provides a safety net for infants exposed to hepatitis B virus (HBV) during delivery or in early life. Hepatitis B vaccine is recommended in the United States for infants prior to birthing facility discharge, and within the first 12h of life for infants born to hepatitis B surface antigen (HBsAg)-positive mothers. We performed a literature ...

The 37-kDa protein (P37) of Borrelia burgdorferi is an antigen that elicits an early immunoglobulin M (IgM) antibody response in Lyme disease patients. The P37 gene was cloned from a B. burgdorferi genomic library by screening with antibody from a Lyme disease patient who had developed a prominent humoral response to the P37 antigen. DNA sequence analysis of this clone revealed the identity of ...

brucellosis, produced by brucella species, is a disease that causes severe economic losses for livestock farms worldwide due to serious economic and medical consequences of this disease, many efforts have been made to prevent the infection through the use of recombinant vaccines based on brucella outer membrane protein (omp) antigens. in the present study, a wide range of on-line prediction sof...

introduction: toxoplasma gondii is a protozoan parasite which is globally prevalent in human and animals. toxoplasma infection is commonly asymptomatic, but can cause serious medical problems in immunocompromised individuals and in fetus. recombinant antigens of the parasite may be helpful in diagnosing the infection more precisely. the goal of this study was to construct and evaluate the funct...

Brucellosis is caused by the bacterium Brucella and affects various domestic and wild species. GroEL (Heat Shock Protein 60kDa) as one of the major antigens that stimulate the immune system, increases Brucella survival. The aim of the current study was to clone and express GroEL in Escherichia coli in order to design subunit vaccine. Amplifying was performed using specific primers. The full-len...

Abstract Chimeric antigen receptor (CAR)-T cells have revolutionized the immunotherapy of B-cell malignancies and are poised to expand range their impact across a broad oncology non-oncology indications. Critical success given CAR is choice binding domain, as this key driver for specificity plays an important role (along with rest structure) in determining efficacy, potency durability cell ther...

introduction and aims: in order to prevent liver cirrhosis and hepatocellular carcinoma in later life, it is essential to prevent hepatitis b virus (hbv) infection in infants. despite the availability of an effective vaccine, hepatitis b still continues to be a significant health problem. the aim of this study is to reveal the efficacy of passive and active immunoprophylaxis for preventing peri...
