THE PROBLEM OF ALLERGIES
A Study of the Immune SystemAn Innovative Solution for
allergies
Allergies affect more people than any other chronic disease
About 50 million people are affected by allergies in the US
Main costs are due to Medications ER visits
But many people are not diagnosed or do not follow the treatment regimen
Allergies are becoming more common
From 1980 to 2010 the percentage of the western population with allergies went up from 10% to 30%
Food allergies are increasing among children
New allergies being discovered Latex allergy
Allergies are expensive Current cost of allergies
about $32 billion Since many people are
not diagnosed, the costs are underestimated
More and more people are becoming allergic
US Healthcare expenditure in billions of dollars
The increase of the overall the cost of treating allergic rhinitis

Allergies are expensive for the victim
Acute flair ups require ER visits Average cost
$1,038 Continuous cost of
chronic problems Antihistamines Topical-steroids Epi-pens Over $200 /month
Allergies compromise the lifestyle of the
patients Stay on constant vigilance
On medication at all times Ingredients in foods Indoor or outdoor activities Carry epi-pens and know how
to administer them Opportunity cost
About 3.8million lost school and work days because of allergies annually

Allergies and co-morbid conditions
People with allergies often have other chronic diseases Average person with
allergies has 2.3 co-morbid conditions
The most common co-morbid condition is hypertension

Prevention is better Envirobots has come up with an
innovative solution. We will modulate your immune
system to react differently to harmless allergens
Obvious benefit for allergy patients Other immune system diseases can
benefit in the future Auto immune, cancer, AIDS, organ
transplant recipients
Reasons for increase in Allergies
Increase in cleanliness By constantly washing up, we are
underexposed to dust, pollen, and other common allergens.
Our body now incorrectly classifies those substances as antigens
Limited exposure to animals Animals possess endotoxins- a bacteria
that helps prevent allergies and diseases Technological developments expose
us to more chemicals
Environmental Pollution When pollen is coated with chemicals from
burnt fossil fuels, the allergic reaction intensifies Healthy lifestyle is sacrificed for
convenience People are not going outside anymore
Computers and videogames keep people inside Less exposure to allergens makes people more
allergicGames like Farmville are replacing actual hobbies like gardening.
Reasons for increase in Allergies
Allergy type Data in the USAllergic rhinitis 35.9 million (about 11% of the population[75])
Asthma10 million suffer from allergic asthma (about 3% of the population). The prevalence of asthma increased 75% from 1980-1994.
Atopic eczemaAbout 9% of the population. Between 1960 and 1990 prevalence has increased from 3% to 10% in children.[78]
Anaphylaxis
About 40 deaths per year due to insect venom. About 400 deaths due to penicillin anaphylaxis. About 220 cases of anaphylaxis and 3 deaths per year are due to latex allergy. An estimated 150 people die annually from anaphylaxis due to food allergy.
Insect venomAround 15% of adults have mild, localized allergic reactions. Systemic reactions occur in 3% of adults and less than 1% of children.
Drug allergies Anaphylactic reactions to penicillin cause 400 deaths per year.
Food allergiesAbout 6% of US children under age 3 and 3.5-4% of the overall US population. Peanut and/or tree nut allergy affects about three million Americans, or 1.1% of the population.
HOW DOES THE IMMUNE SYSTEM
WORK?
Our Immune System The Immune system was discovered in
the Plague of Athens in 430 BC Protects us against anything that attacks
the body White blood cells guards against
External pathogens like viruses and bacteria Internal tumors
The Immune System offers three layers of protection
1st •Physical barriers
2nd •Innate immune system
3rd •Adaptive immune system
Physical BarriersPrevent pathogen
entrance The skin acts like a
ceran wrap Other openings in
the body are protected E.g. nose
Pathogens that do get in get excreted/destroyed
Body secretions Saliva, mucus, urine,
faeces, tears Chemicals like
stomach acid destroy bacteria
Gut flora prevent colonization of pathogens

Nose hairs filter out particles
Innate Immune System
Parts FunctionPhagocytes Engulfs antigensBasophils Contain
histamineNatural Killers Kills antigensDendritic Cells Bridge to
adaptive systemComplement System/cytokines
Proteins that attract phagocytes release histamine
Histamine is secreted by Mast cells
Vasodilation increases blood supply
Phagocytes attracted by complement
Complement helps phagocytes engulf and also release histamine
Macrophage
Instantaneous, inflammatory response to antigens
Adaptive Immune System
PartsMajor Histocompatibility Complex (MHC or HLA)Helper T cells Killer T
cellsB Cells Antibodies
Histamine is secreted by Mast cells
Vasodilation increases blood supply
Phagocytes attracted by complement
Complement helps phagocytes engulf and also release histamine
B Cell with antibodies
Tailored responses to specific antigens
Summary
The person’s body now “remembers” the pathogen, so he knows what to due in future
Adaptive Immune System response: a pathogen-specific attack is started
Innate immune System Response: A generic response is initiated
The foreign substance gets past physical barriers
The pathogen attacks!
DETAILS OF THE IMMUNE SYSTEM
Major Histocompatibility complex (MHC)
The adaptive immune system uses the MHC molecules to find antigens
The MHC molecules are able to display proteins on their surface
T-cells use these protein displays to identify the antigens
Aka Human Leukocyte Antigen
B Cells
Have receptors called antibodies on surface where antigens attach
Initial response Antigen attaches to a receptor
stimulating B cells to divide Some B cells change into memory cells,
to remember the specific antigen Others change into plasma cells that
produce antibodies for the next attack Secondary Response
If the B cells comes into contact with the allergen again they quickly multiply
Antibody
T Cells Learn to distinguish self from non self
cells Three types
Killer T cells attach to foreign or abnormal cells (having encountered them before) and kill these cells through a method of puncturing the cell and injecting enzymes to kill them
Helper T cells recognize the antigen and summon the B cells and killer T cellers
Suppressor T cells produce chemicals to stop the immune response
• Initially, a T cell can’t recognize an antigen in the body because it is too big to fit into the T-cell receptor.
• MHC molecules link with the smaller antigen fragments, and present them to the T-cell receptors
• The smaller fragments understandable by the T-cell, which begin the defense
• Enzymes within the dendritic cell break the antigen into little fragments.
• A dendritic cell, which can process antigens, digests it.

IMMUNE SYSTEM MISTAKES
When the immune system makes a mistake
The Immune system can make mistakes False detections of external pathogens
result in allergies False detection of internal tissues can
cause auto-immune diseases
You sneeze when you get allergies
• Sometimes the immune system makes a mistake and thinks a harmless product is antigen
B cells and antibodies are activated• Killer T cells are
activated
The body has just initiated an Inflammatory Response
• IgE binds to the mast cells
• The mast cells de-granulate and release the histamine in them
• The MHC helps display the antigen to the T cells who recognize it as non self
• The peptide signal is displayed
THE ENVIROBOTS SOLUTION
The EnviroBOSS Solution Consists of a set of nano-bots
introduced into the blood stream The nanobots stop the allergic
reactions
A control arm band Allows the antigens to be configured
for the nanobot Allows for a manual over-ride in case
of emergency
How Does it Work? Stops the attack even before it starts The nanobots recognize the peptide
combination presented by the MHC and break it down before the antigen is presented to the T cells Destroys peptide signal to helper T cells
The Arm band has different signals for different peptides programmed into it
EnviroBOSS destroying the antigen presentation
EnviroBOSS Arm Band The arm band is like a
control center program peptide
combinations using a easy to use user interface
Communicates with nanobots using high frequency microwaves which are reliable and don’t hurt your body
Manual override Panic button releases
epinephrine in case of emergency
Antenna for communicating with nanobot
Epinephrine
The EnviroBOSS Nanobots Multiple nanobots are injected
into the bloodstream The nanobot is programmed to
recognize the amino acid/peptide combinations, which represent the user’s allergies.
The robot motor is made from grafted heart muscles and powered by the patient’s blood sugar
When a programmed protein combination is recognized by the nanobot it destroys the protein preventing the immune system reactions

ENVIROBOTS AGAINST EXISTING TREATMENTS
(Alternate treatments)
EnviroBOSS vs. AntihistaminesANTIHISTAMINES ENVIROBOSS
Histamines are still present, so brain stays alert and awake
Body doesn’t adapt to nanobots
Emergency should not even arise but the epinephrine panic button is easy to use in emergencies
Drowsiness in older antihistamines
Body adapts to antihistamines and you need a new one every few months
No good in emergencies
EnviroBOSS vs. Immunotherapy
IMMUNOTHERAPY ENVIROBOSS
Immediate effect after treatment
Works with all allergies
Emergencies should not even arise but the epinephrine panic button is easy to use in emergencies
Takes a long time to take effect
Does not work in food allergies
No good in an emergency
