#Immunity in simple terms:
1. Innate immunity
Physical barriers = shuts door on intruder
Non specific defences =kills any intruder soon after entry
2. Acquired immunity
Learn to kill a specific foe = system has to learn to identify and tailor make antibodies, needs time
Physical barriers = stickiness of nasal passage, the slime, intactness of skin etc : Tries to see if the doors can remain shut
(Now if you are clever you erect further barriers you #MaskUp)
Non-specific immunity = kills 'any' intruder, starts straight away: system we share with plants /animals
Foreign protein sighted->
Chemical cascade-> kill, recruit killer cells, signal virus infected cells to rapidly kill themselves!
+send signals to next line of defence

(01/31) The late film critic @ebertchicago was not a huge fan of @rolandemmerich’s “Independence Day”. His review of the larger-than-life, schmaltzy blockbuster noted that it was little other than “silly summer fun”, which was reluctant to “slow down for the small details”.
(02/31) ‘Not slowing down’ is very much part of the modus operandi of blogger, hat model and occasional-#PrimeMinister Dominic Cummings. Particularly when maximising the fuel efficiency of the vehicle transporting his symptomatic family to medical facilities in Northern England.
(03/31) Cummings favours haste, brevity and a broad-brush approach over ‘the small details’. This is perhaps best demonstrated by his relentless promotion of catchy-yet-meaningless slogans, such as #StayAlert, #GetBrexitDone and #ConsiderTheMatterClosed.

So, this Electrek article about Tesla cancelling Solar Roof orders AFTER YEARS of taking deposits, is blowing up my DMs.

Here's why:

#TheSociopathicBusinessModel #FraudFormula $TSLA #SolarCity
#ElonMusk #DOJ

1/5
When a company, like @Tesla is under @TheJusticeDept criminal investigation, and does something #inconsistent & #contradictory to generating revenue, it's "usually" a sign of negotiation behind closed doors.
2/5
$TSLA #TheSociopathicBusinessModel #FraudFormula #ElonMusk
Meaning the "company" is agreeing to cooperate with the DOJ to stop illegal activity to avoid criminal charges; and, will eventually when the case is out from under seal, pay a civil fines.

1. Mandated #MRNA vaccines are coming. fool.com/investing/2020… The fear campaign of #Covid19 has failed. People are not scared any longer of #Covid, but that's not the problem anymore and truthfully Covid never was.
2. The problem is now that #Covid failed and you are
seeing this chess game of #totalitarian control unfold,
let me tell you what is really coming. If this is a
#mandatoryvaccine campaign and it gets rolled out
rapidly, you better be aware, educated and terrified.
3. #Globalists in the next 2-3 months will magically find the
cure for #Covid and roll it out in a mass #vaccination
campaign. This #vaccine is #MRNA vaccine. This roll out
will come out very fast for two reasons.

. @CovidIndiaSeva I beg your kind attention here ! If we look at proportion of #Covid_19india patients on #ventilator support, it is 0.4% to 0.5%, which reflects ARDS due to Pneumonia due to #COVID19 as cause of death (COD) ( @WHO code: U07.1/2)... 1/n
So, around 150 deaths in 3000 projected deaths are actually due to #Covid_19india Epiphenomenon: People with diabetic complications, advanced cancer etc where the main COD is underlying health conditions, but #COVID19 can only be a contributing cause .. 2/n
Vast majority of #COVID19 deaths in India could be an epiphenomenal death only, considering #BCG vaccine induced trained #Immunity (Nature paper link at the end of this thread) that offers protection from severity of #Covid_19india . Why I am saying this is more important.. 3/n

Asians & others with darker skin living in Northern latitudes are prone to Vitamin D Deficiency? Severe COVID19 males had lower vitamin D levels. (Females take more supplements) Vitamin D plays key roles in cardiovascular & immune systems 1/n #VitaminD

Vitamin D regulates the expression of PLC-γ1 in naive T cells & is key to T cell responsiveness in humans. Poor primary T cell response can affect immune responses to viral infections including influenza & coronaviruses. 2/n @Ms_Aflatoon #VitaminD

Vitamin D necessary for IFN-γ–induced antimicrobial peptide cathelicidin expression, autophagy, phagosome-lysosome fusion, and antimicrobial activity crucial to TB & leprosy immunity. Before antibiotics sunlight was the only treatment for tuberculosis 3/n

For all those who argue as nauseum about #lowcarb !! I'm a doctor and I'm not an idiot to tell people to stay off medicines and focus on inner immunity and health. All my life I struggled with a hypocaloric high carb diet. That's why I feel deeply about this whole topic. #health
I was a plump child and was always told to eat less and exercise more. I was always hungry. I grew up to a fat teen with a terrible body image. It drives me up the wall to see people unnecessarily arguing about the so called balanced diet. I tried all gimmicks : Alas
Thank God that I came across #IntermittentFasting and #lowcarb. It's never about #weight. It's about #Health. #weightloss and a #positiveattitude is the by product.
Thank you to all those who have been a part. I'm 3 years menopausal now. And pretty much fit for my age. #fit

#SARSCoV2 There are several kinds of #vaccines, whereby all share the goal of generating adaptive #immunity via 1) #antibodies via B cells, and 2) T-cell receptors (#TCRs) via T cells:
1) live-attenuated, where you produce an actual #virus in an egg or cell line
2) #recombinant, where you introduce #DNA into yeast, bacteria, or cell lines — you produce pieces of the #virus #proteins, then either administer them as-is or typically by linking them to immunogenic substrates like albumin, BSA and KLH

There is a lot of discussion about whether #coronavirus infection will result in long-term #immunity. We don't yet have data on this, but in the meantime, a brief discussion of some types of immunity that we might see. (thread)
1. Sterilizing immunity--this is the best-case scenario. Sterilizing #immunity means that the body is able to prevent reinfection entirely. Viruses may enter the body, but they are unable to infect cells, replicate, or otherwise cause harm or further spread.
2. Immunity with limited viral replication. This would mean the people could get reinfected but it would involve lower levels of virus production. This often has important benefits for both decreasing severity of illness and limiting spread of infection to others.

Some have suggested that detection of #SARSCoV2 antibodies could be a basis for an “immunity passport” / “risk-free certificate” that will enable individuals to return to work. Currently, there is no evidence those who have recovered from #COVID19 are protected from re-infection.
Immunity to a pathogen through natural infection is a multi-step process that usually takes place over 1-2 weeks. The body responds to a viral infection immediately with a non-specific innate response: macrophages, neutrophils, dendritic cells slow the progress of the virus.
This non-specific response is followed by an adaptive response i.e. body makes #antibodies that specifically bind to the #virus. These #antibodies are proteins called #immunoglobulins. The body also makes T-cells that recognize & eliminate other cells infected with the virus.

Lets talk about #Immunity as #Coronavirus is here to stay for a while.Building immunity is a long-term process.Cant be achieved overnight.
Dietary Measures you need to take -
1)Eat Wholesome with emphasis on Protein in Every Meal. Both protein quality & quantity matters
#Thread
2) Vitamin C rich foods like amla,guava,oranges,lime juice or raw greens to be had daily.Note- Heat destroys Vit C.

3) Vitamin A rich foods like eggs, milk & milk products.Or Beta carotene ( precursor of Vit A ) in colorful fruits , veg are important
#Immunity #CoronaPandemic
(iv)Minerals like Zinc,Selenium in the diet are crucial. Sources include nuts,seeds,pulses,whole grains,eggs,meat ,fish,etc.
(v)Fibre -Include good quantity of vegetables,whole fruits,whole grains & pulses in the diet. Gut health should be taken care of.

THREAD: I was sad, but now I am angry. As clinicians, we have the enormous privilege of attending to people when they are at their worst. Death, loss, disease, events that alter the trajectory of people’s lives, and keep working, because there is always work to be done. 1/
We ease the suffering of #humanity. That is what we have been called to do. And I feel like part of that is that we often censor ourselves to protect non-medical people. But how about we start to share a tiny glimpse of our reality? (Medical terminology is in quotes) 2/
While we know that 80% of cases are mild, do you know how people die after being infected with “Severe Acute Respiratory Syndrome #Coronavirus 2” (#SARS_COV_2)?

Rather, do you know how the majority of people who are deceased as a result of the new Coronavirus, perished? 3/

1/ I have corrected my assumption of herd #immunity being achieved at 70% of population to 60%. Extrapolation was made under further simplified assumptions:
* full disclosure of all cases,
* unchecked spread,
* maximum mixing
Estimated time course of #COVID19 cases in #Germany:
2/ Extrapolation of daily #COVID19 cases in Germany:
3/ Estimated daily hospital admissions of #COVID19 cases in Germany under assumption of 5% hospitalisation rate. Note: Germany has 500,000 hospital beds.

There's a seasonality to many respiratory #viruses. Will #SARSCoV2 [#COVID19] follow a similar pattern? We hope so BUT we don't really know. We know when air is humid / warm ➡️droplets gather more moisture ➡️too heavy to stay airborne / fall more quickly➡️transmission harder.
There was a significant correlation between #SARS cases & environmental temperature. A sharp rise or decrease in the environmental temperature related to the cold spell led to an increase of SARS cases because of the possible influence of the weather on the human immune system.
Plus the winter season has a profound effect on how human #genes work - this may explain why some illnesses are aggravated in the #winter. During cold, winter months, genes involved with #immunity & specifically #inflammation were more active. nature.com/articles/ncomm…

Happy to be back in Sweden for my 2nd #BiologyofSperm meeting & hearing fascinating stories on evolution of sperm, gamete interactions, reproductive organs and strategies by fellow #spermnerds
#BoS2019 #BoS15
Started strong yesterday with Sabine Koelle showing us the very first live imaging movies of sperm behavior in human reproductive tracts, all the way to the fertilization site, and even sperm filmed live swimming inside the testes! What a cool talk!
Next @lross_evoento told us about (incomplete) paternal genome silencing in fascinating mealybugs. @emwhitti brought us to the amazing world of Post-Ejaculatory Modifications w/ impressive proteomics data from 1000s of #drosophila reproductive tract dissections. #BoS2019 #BoS15

#mdpidiagnostics #pwME #chronicillness #SickNotWeak #MyalgicE
mdpi.com/2075-4418/9/3/…
1. Is there a genetic susceptibility which leaves some individuals vulnerable to #MECFS after exposure to a virus, bacteria or toxic chemical?

#pwME #chronicillness #SickNotWeak #MyalgicE @diagnostic_mdpi #medtwitter #genetic
2. What is the key initial physiological trigger causing the dramatic downward spiral in health leading to #MECFS?
