Bengaluru, Mar 28: Sun Tsu, in 'The Art of War' speaks of a skilful general who can subdue his enemy without any fighting. This constitutes the ultimate triumph which is referred to as stratagem. Today, we would need one such when we are faced with the '21-day corona challenge' for India.
Nearly four weeks back, Dr Jyothsna Rao, Dr Gururaj Rao and I sat across the OPD in the afternoon at HCG Bengaluru discussing our ongoing cancer immunology research. While on this topic, we drifted into the discussion on the coronavirus. During this engaging discussion, we wondered the similarity of the enigma between the virus and cancer. I paused to ask Dr Jyothsna and Dr Guru - how we wish we could do something against this virus.
Dr Jyothsna is a PhD from NCBS and had worked under Dr Ralph Steinman, physician and researcher from Rockefeller University, who won the Nobel Prize for his discovery of the dendritic cell and its role in adaptive immunity in 2011. Dr Gururaj is a molecular and cell biologist who did his PhD at the Chapel Hill, University of North Carolina and is the Director of iCrest.
Jyothsna while hearing our perplexing conversation on the covid intervened, "Yes, surely. I think we should take a break from cancer and focus on the innate and adaptive immunity role in COVID-19."
Thus began this sincere attempt to relook the human immune system from the eyes of the COVID-19.
We have 10 types of immune cells at the least which are widely dispersed in millions across the body. When our body is invaded by a foreign organism (bacteria, fungi or virus), these cells work with each other to destroy the invader.
Now, the question is - how do the immune cells talk to each other? They use small-molecule substances called cytokines (cyto means cells; kine means movement). There are many cytokines that are involved in work on the immune system. The most relevant for viruses are interferons.
Interferons (IFN) as the name reflects have an ability to interfere with the viral activity and stop their multiplication. These specialised signal proteins are released by our cells in response to a viral attack to forewarn other cells. They help build the antiviral proteins within the cells to kill the virus as it tries to invade the new cells.
Historically, interferons are a group of cytokines known to be potent antiviral agents against viruses and a hallmark cytokine induced by the host upon viral infections. Interferons possess unique immunoregulatory activities and are signature cytokines released by (TH1) T immune cells, which are crucial in viral infections.
As the outbreak of COVID-19 grapples us, an urgent need for finding strategies to combat the virus is growing. Coronaviruses (CoVs) are a group of RNA viruses. In patients infected with coronavirus, it was indicated that the activation of the IFN does not occur until 48 hours post-infection. Thus the delayed IFN-related antiviral response by the healthy cells leads to coronavirus evade the immune response.
Numerous studies have presented the success in defeating CoVs by the direct administration of IFNs. In a combination as a concoction, it was shown to synergistically inhibit the virus replication in vitro.
Moreover, it is understood that the earlier induction of IFNs in children although they have a less developed immune system could be the reason behind the children being least affected.
The key to success in reducing the disease fatality might be the stimulation of the immune responses to trigger IFN production at the very early stages of the disease, which might be done through the administration of IFN. Despite the evidence for the efficacy of IFNs in treating CoV-induced infections, the proper dosing and ideal timing for such interventions needs to be verified in clinical trials.
For the later stages of the diseases in advance stages where patients are on ventilator and have developed respiratory distress, we propose to utilise the mesenchymal cells derived from donor bone marrow that have been known to treat acute respiratory syndrome. Mesenchymal cells are known to possess anti-inflammatory activity and thus used often in autoimmune diseases.
With this scientific background, we have activated T cells from healthy donors, in a cGMP facility at iCrest - HCG hospital with an enriched cocktail of cytokines rich in Interferons. Injections of this cocktail we believe will result in a surge of cytokines in the body of the infected person and will boost his ability to fight the virus in the early phases. We are in the initial phases of this study and hope to be ready in the coming weeks with meaningful data on its potential utility.
Currently, it awaits government approvals (Union and state) and we have applied to central drugs authority for their initial evaluation and further directions.
As my Guru often expounded the philosophy of 'Seva' - the goal of education is knowledge, the end goal of knowledge is service. In this attempt to serve our fellow humans at this brink of unprecedented crisis, medical fraternity stands with you and promises to do our best for your safety.
We assure to exhaust every bit of our spirit in this fight against coronavirus. We have lost the sight of shores and travelled thus far, but that is the mandatory first step to cross the ocean. Are we going to succeed in this battle, is something only time will answer.

corporation lights of cemetrey not glowing since two months. On 1st November 2019 is holy souls day. Kindly repair the lights at the earliest.

hello / madam
Keeping the city clean is our duty. I know not everybody is following that. We need some awareness program
to keep our city clean green and hygenic. Its our duty to keep the environment clean and place around us.
But it is also the duty of Corporation to maintain the cleanliness aroud the city, in some parts of the city like market, near clock tower circle its not been getting cleaned from past few days. Please do the needfull for betterment of tomorrow
thank you
Dear Madam, I have purchased 1 BHK flat in Green City, Vamadapadav on October, 2013 and paid full amount to builder T3 Urban Developers LTD. As per agreement possession was in December, 2015 but still building is not ready.
There were 5 buildings in Green City and at a time builder started 3 buildings construction work. I have purchased middle of the building and that building 1st floor slab only completed and since long time work stopped.
Last year builder agreed to give me flat in 1st building but building’s interior work is still pending and since 1 year work totally stopped.
Presently builder is not picking call or not responding for query. It seems that he is cheating with me. Kindly help me to resolve this issue. I will be grateful to you.
Sir/Madam,
Four street lights are not working on Raghavendra Matt Road, Hosabettu, Surathkal since long.
The roads are in Shabby condition and hence difficult in the night to Padastrians.
Kindly arrange to replace the treet lights on Main road, Raghavendra Matt Road, Hosabettu, near and after the Areca Field.
the kalbavi road in kottara ashok nagar was provided with ugd pipe line during last year. as usual the centre of road was dug up in march 2018 for this purpose making the road not motorable during the monsoon of 2018.
the asphalt work is now planned now during nov2018 by mcc. this road is very narrow and not having the foot path or road side drain at all.
both the ugd agency as well as the asphalting agency have put the muck/soil on the sides of the road, making it now impossible to walk when there is traffic. also during monsoons , storm water from the entire stretch for about 500 ft will flow on this road itself which is diverted to my compound/pure water sump due to the faulty work of mcc.
in spite of repeated requests/complaints to the commissioner,corporators, engineers of mcc, publishing of the photos of the same in some news papers,action is yet to be taken.
now at least it is requested to remove all the above dumped muck /soil on either sides of this road which is also preventing the entry of monsoon water th the existing drain near the starting point of sagar court.
Street light not working at kulai kavinakallu 2nd street
Relevant department has to look into the matter seriously and work on it and mark the matter as closed so that its notified as closed. Its a good move for public and public workers to work hand in hand
