Abstract

Immune balance during infection is important to support both the defense of body immune system and prevent excessive immune response. Protein Foxp3, a transcription factor of regulatory T cell has pivotal roles in balancing body immune system. Honey and Propolis have proved their effects to both the proinflamatory and anti inflammatory responses but their effects to the Foxp3 expression need to be investigated. This study was investigated the effect of giving Trigona honey and honey propolis Trigona to the mRNA Foxp3 expression in Balb/c mice induced Salmonella typhi. Results of the study indicated that honey propolis Trigona had the highest effect to the mRNA Foxp3 expression followed by Trigona honey. Both Trigona honey and honey propolis had immunomodulatory effects through the Foxp3 mRNA expression.

Abstract

Zika virus (ZIKV) is positive sense single stranded RNA of Flavivirus genus belonging to the Flaviviridae family. It has neither drug nor protective vaccine, and considered to be in relatedness to neurological abnormalities such as Guillain Barre Syndrome and microcephaly of neonates. The aim of this study is to analyze envelope glycoprotein E of all Zika strains using in silico approaches looking for conservancy, which is further studied to predict all potential epitopes that can be used after in vitro and in vivo confirmation as a therapeutic peptide vaccine. A total of 50 Zikavirusvariants’(include 12from South America) polyproteins retrieved from NCBI database were aligned, and the conserved regions of Envelope Glycoprotein-E were selected for epitopes prediction. IEDB analysis resource was used to predict B and T cell epitopes and to calculate the population coverage. Epitopes with high scores in both B cell and T cell epitopes predicting tools were suggested. Three epitopes were proposed for international therapeutic peptide vaccine for B cell (AQDKP, TPNSPRAE and TPHWNNK) and two other epitopes designed especially for South America strains (LDKQSDTQYV and EVQYAGTDGPCK). For T cell epitopes, MMLELDPPF epitope was highly recommended as therapeutic peptide vaccine to interact with MHC class I along with three other epitopes (MAVLGDTAW, KEWFHDIPL and DTAWDFGSV) which showed very good population coverage against the whole world population. Three epitopes showed high affinity to interact with MHC class II alleles (FKSLFGGMS, LITANPVIT and VHTALAGAL) with excellent population coverage throughout the world and South America region. Herd immunity protocols can be achieved in countries with low population coverage percentage to minimize the active transmission of the virus, especially among pregnant women and other groups at risk.We recommendin vitro and in vivo proving the effectiveness of these proposed epitopes as a vaccine, as well as to be used as a diagnostic screening test.

Abstract

Background: L-glutamate is one of the most common amino acid in nature and it acts as excitatory neurotransmitter in the central nervous system. GRM4 is a large gene located in chromosome 6 and consists of 7217 bp (NCBI) divided into 10 exons. The location of GRM4 (chromosomal segment 6p21.3) is tentative susceptibility loci for Juvenile Myoclonic Epilepsy so many studies investigate the association of GRM4 polymorphism with myoclonic epilepsy juvenile. Design and methods: GRM4 gene was investigated in dbSNP/NCBI database NCBI and we used computational analysis approach. Deleterious nsSNPs were predicted by SIFT and Polyphen soft wares then the damaging nsSNPs were submitted to I mutant tool. Protein structural analysis of amino acid variants was performed by Chimera 1.8 and Project Hope. Results: We analyze 29854 SNPs from NCBI; 8561 of them found on homosapiens; of which 330 were missense, of which 208 were in the coding region, 334 were non-synonymous SNPs (nsSNPs), 232 were in the 3'un-translated region. These SNPs were analyzed using different soft wares; SIFT, Polyphen-2, Imutant3.0, PhD-SNP, PolymiRTs, Project Hope and GENEMAIA to investigate the effect of SNPs mutations on GRM4 protein structure and function. Conclusions: Computational tools were used to analyze deleterious SNPs in GRM4 gene. Out of 8561 SNPs, the SNPs (rs184636998), (rs199744441), (rs199744441), (rs149277708), (rs144660534), (rs139236496) were identified as highly damaging in coding region confirmed by using bioinformatics tools . In 3'un-translated region two SNPs (rs188406833) and (rs192860479) contained (C) allele had 4 miRSite as target binding site can be disrupts a conserved miRNA and one SNPs (rs77415386) contained (D) allele had 6 miRSite as derived allele that disrupts a conserved miRNA site. Further study must be done to detect the effect of these SNPs on the protein structure and function.
