The insulin-like growth factor-1 receptor (IGF-1R) is a transmembrane receptor with tyrosine kinase activity. The receptor plays a critical role in cancer. Using monoclonal antibodies (MAbs) against the IGF-1R, typically blocks ligand binding and enhances down-regulation of the cell-surface IGF-1R. Some MAbs such as cixutumumab are under clinical trial investigation. Targeting multiple distinct...

Protective antigen (PA), a subunit of anthrax toxin from Bacillus anthracis, is known as a dominant component in subunit vaccines in protection against anthrax. In order to avoid the side effects of live attenuated and killed organisms, the use of linear neutralizing epitopes of PA is recommended in order to design recombinant vaccines. The present study is aimed at determining the dominant epi...

Streptococcal bacteria are among dangerous human pathogens with major prevalence worldwide. A good vaccine against streptococcal bacteria should have epitopes that confer protection from infection by different streptococcal bacteria types. we aimed was to recognize the most immunogenic and conserved epitopes of streptococcal bacteria, which could be a potential candidate for vaccine development...

background: boophilus tick is responsible for the transmission of some pathogens (types of germs) and the reduction of fertility in cattles. tropomyosin protein plays an important role in regulating actin function, immune and allergic reactions and vaccine production. objectives: accurate identification of antigenic determinants (epitopes) is difficult, time consuming and not economic, thus we ...

Background and purpose: In 2019, the world has witnessed the emergence of a virus that caused acute respiratory distress syndrome in human with high mortality rates (approximately 3.7%). So far, no effective treatment has been proven against COVID-19. This study aimed at designing a multi-epitope vaccine combining several T-cell and B-cell epitopes of the SARS-CoV-2. Materials and methods: Bas...

Background & Aims: Antibodies, well-known as immunoglobulins (Igs), are produced by B lymphocytes and specifically defend against pathogens. Igs are glycoproteins and have high diagnostic value in several diseases including infections (1). Igs are composed of light and heavy chains (2, 3). Each chain is comprised of about 110-120 amino acid residues which create immunoglobulin folds named domai...

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...

Abstract Background: Naturally occurred hepatitis B virus (HBV) with surface mutations in a variety of chronic hepatitis B (CHB) patients who have received no vaccine or HBIG bearing substitutions in surface protein, have been reported. Objectives: Current knowledge concerning the prevalence of these naturally occurring surface antigen mutations among Iranian carriers is limited. Patients and M...

Objective(s) The aim of this study was to characterize the hepatitis B virus surface protein genotypes and sequence variations among hepatitis B virus surface antigen (HBsAg) positive chronic patients in Hormozgan province, south of Iran. Materials and Methods A total of 8 patients enrolled in this study. The surface gene was amplified and directly sequenced. Genotypes and nucleotide/amino a...
