Brucella melitensis is an organism of paramount zoonotic importance. The 28 kDa outer membrane protein (OMP) is one of the immunodominant antigens of B. melitensis. The gene encoding 28 kDa OMP (omp28) has been amplified from B. melitensis Rev. 1 strain. A PCR product of 753 bp, encoding complete omp28 gene of B. melitensis, was obtained. The gene was further cloned and sequenced. The nucleotid...

Background: Triple-negative breast cancer (TNBC) is determined by the absence of ERBB2, estrogen and progesterone receptors’ expression. Cancer vaccines, as the novel immunotherapy strategies, have emerged as promising tools   for treating the advanced stage of TNBC. The aim of this study was to evaluate Carcinoembryonic antigen (CEA), Metadherin (MTDH), and Mucin 1 (MUC-1) proteins as vaccine ...

The nucleocapsid (N) protein of rinderpest virus (RPV) is one of the most abundant and immunogenic viral proteins expressed during natural or experimental infection. To identify immunogenic epitopes on the N protein, different forms of RPV N protein, including the full-length protein (N(1-525)), an amino-terminal construct (N(1-179)), and a carboxy-terminal construct (N(414-496)), were expresse...

A crystal structure is reported of the peptide Ac-Ala-Asn-Pro-Asn-Ala-NH2, representing the immunodominant region of the major surface protein on the malaria parasite; the NPNA motif adopts a type-I beta-turn, which is stabilized by hydrogen bonding between the CO of Asn2 and the NH of Ala5 as well as between the O(delta) of Asn2 and the NH of Asn4.

We have cloned and characterized the gene for an immunodominant antigen of O. volvulus that is recognized by the sera of 96% of patients with onchocerciasis. Its 1.2-kb mRNA constitutes 0.3% of adult worm poly(A)+ RNA and its cDNA sequence reveals that it is not a highly conserved structural protein such as actin or tubulin. Similar but not identical genes occur in the genomes of related filari...
