-: The body can recognize proteins as foreign ones.

-: Our digestive apparatus breaks the proteins in our food into amino acids.

-: All living tissue needs about thirty kinds of amino acids.

-: Amino acids are absorbed into blood.

The role of protein in allergy.

Proteins are fundamental parts of the structure of all living material. A great variety of them make up an essential part of the food we eat. Our digestive apparatus breaks the proteins in our food into their basic structural units, simpler substances called amino acids. These amino acids are then absorbed into our blood, carried around the body, and reassembled into our own individual body protein. It is if you took a brick wall apart down to its individual bricks, transported them to a new location, and then put them together to form a different wall.

Each person’s individual proteins are different from any other person’s. We may call them self- proteins. They are basic to making you yourself. They are very different, too, from bumble- bee protein, or mouse protein, or the protein of corn or egg white, cow’s milk or, indeed, any other protein.

Nevertheless, all these proteins are built of amino acids, just as all brick walls are built of bricks. All living tissue needs about twenty kinds of amino acids from which to build its own kinds of protein.

If instead of amino acids, some undigested protein is absorbed or injected into blood, the body recognizes it as a foreign protein and wants no part of it.

-: Early in the course of the disease, the most of the symptoms are digestion-related.

-: Other symptoms include emotional problems.

-: PD is a disorder of the central nervous system.

-: The disease can be either primary or secondary.

Parkinson’s Disease.

Parkinson’s disease (PD) is a degenerative disorder of the central nervous system mainly affecting the motor system. Early in the course of the disease, the most obvious symptoms are movement- related; these include shaking, rigidity, slowness of movement and difficulty with walking and gait. Later, thinking and behavioral problems may arise, with dementia commonly occurring in the advanced stages of the disease, and depression being the most common psychiatric symptom. Other symptoms include sensory, sleep, and emotional problems. The main motor symptoms are collectively called «parkinsonian syndrome».

The disease can be either primary or secondary. Primary Parkinson’s disease has no known cause, although some atypical cases have a genetic origin. Secondary parkinsonism is due to known causes like toxins. Many risks and protective factors have been investigated: the clearest evidence is for an increased risk in people exposed to certain pesticides and a reduced risk in tobacco smokers. The motor symptoms of the disease result from the death of cells in the substantia nigra, a region of the midbrain. This results in not enough dopamine in these areas. The reason for this cell death are poorly understood but involves the build-up of proteins into Lewy bodies in the neurons.
