Marking Criteria Assessment

Case Scenario/ Task

For the paper, mainly there are 3 key findings and they are :

1. Primate transferrin experienced repeated positive selection at the binding boundary with bacterial TbpA

2. Transferrin divergence in humans and chimpanzees causes the TbpA binding site to be reversed and impaired

3. The genetic variation in the TbpA of some human pathogens (e.g., Haemophilus influenzae) is evaded due to the C2 transferrin polymorphism in humans For the structure of the powerpoint presentation, we can go with the following order:

Introduction

Key finding 1

Key finding 2

Key finding 3

Conclusion

Limitations

{*** offer code can be varied from 1-5***}

Introduction:

Iron sequestration gives a characteristic barrier, termed dietary safety, driving pathogens to search iron from hosts. Despite the fact that the atomic premise of this fight for iron is set up, its potential as a power for advancement at host-pathogen interfaces is obscure. the iron transport protein transferrin is occupied with antiquated and progressing transformative clashes with TbpA, a transferrin surface receptor from microscopic organisms. Single substitutions in transferrin at quickly developing destinations reverse TbpA official, giving a instrument to neutralize bacterial iron robbery among incredible gorillas. Besides, the C2 transferrin polymorphism in people dodges TbpA variations from Haemophilus influenzae, uncovering an utilitarian premise for standing hereditary variety. These discoveries distinguish a focal part for nourishing insusceptibility in the persevering developmental clashes between primates and bacterial pathogens.

Iron transport in vertebrates is affected by serum transferrin, which is a protein that holds circulating iron contents and then pass it onto cells via the endocytosis which is receptor – mediated. Other significant functions of transferrin is to contribute to hosting nutritional immunity by gathering necessary iron which is far from microbial pathogens. The role of transferrin in transport of iron enhances functional conservation that may delay adaptation against the iron piracy.

In this research, the researchers successfully cloned and also sequenced transferrin orthologs by making use of 21 different hominoids in order to find out if transferrin is affected by evolution of pathogen – driven in the primate – lineage. 21 hominoid species collected were of new world and old world monkey species and were used for phylogenetic analysis. A blend of greatest likelihood–based calculations to evaluate proportions of non - synonymous to synonymous substitution rates (dN / dS) uncovered solid marks of long winded positive determination in transferrin over a few branches of the primate ancestry. To date, such marks of sub-atomic "arms races" in vertebrates are essentially archived among cell surface receptors and inherent example acknowledgment proteins threatened by infections (6–8), mirroring the power of such host proteins as "cutting edge" insusceptible barriers or purposes of passage for infections.
