Introduction:What they say

A recent study from Cell Signalling Section, Division of Immunology, Department of Pathology, Tennis Court Road, University of Cambridge, Cambridge CB2 1QP, UK shows that “Glycogen Synthase Kinase 3 Inactivation Drives T-bet-Mediated Downregulation of Co-receptor PD-1 to Enhance CD8(+) Cytolytic T Cell Responses.” This study was published in the 16 February 2016 issue of Immunity (one of the best journals in Immunology with an impact factor of 20+) by Prof Rudd CE, Taylor A and others.


What we say

price-quote

On the foundation of this interesting finding, Dr L Boominathan PhD, Director-cum-chief Scientist of GBMD, reports that: Natural product-based PD-1 pathway blockade for Human cancer therapy:  Eriocitrin, found in lemons , decreases the expression of Glycogen synthase kinase-3β, increases transcription factor T-bet expression, decreases the abundance of co-inhibitory receptor PD-1 on the cell surface of Cytotoxic-T-cells, increases cytotoxic T lymphocyte function and augments anti-tumor activity, via up-regulation of its target gene


What is known?

It has recently been shown that blocking PD-1 with antibodies one could make tumors shrink. This work, relating to Cancer immunotherapy, has been chosen as Science’s breakthrough of the year.


Research Findings

This study suggests a natural product-based Human cancer therapy.

Eriocitrin

The study presented here suggests that, Eriocitrin, by increasing the expression of its target gene, it may suppress the expression of Glycogen synthase kinase 3-β. Thereby, it may: (a) increase transcription factor T-bet expression; (b) inhibit co-inhibitory receptor PD-1 expression;  (c) increase CD8(+) cytotoxic T lymphocyte function; (d) augment anti-tumor activity; & (e) inhibit metastatic cancer progression.


Therapeutic opportunity

Thus, pharmacological formulations encompassing “Eriocitrin or its analogues” may be used to inhibit the progression of tumors.
