The Human Body - A Marvelous Creation
Experts  say that our bodies house one trillion immune cells   rendering the capability to  recognize and deactivate ten million   different antigens (invading viruses  bacteria fungi parasites etc.).   However each of us can be missing as many as 50  000 specific antigen   responses which makes us susceptible to those invaders.
Our  immune system features a blend of five components working   in harmony to fight  infection. These "defenders" include stem cells   B-lymphocytes natural  killer cells macrophages and in command of the   whole process T-lymphocytes. It  is through this combination that   invading antigens are identified targeted  surrounded attacked and   destroyed.
Transfer factors are a  substance within our immune cells specifically   T-lymphocytes that imparts the  "blueprints" of individual antigens.   These "blueprints" or  memories enable T-lymphocytes to immediately   recognize an enemy antigen.
1.Stem  cells are best regarded as maturing cells that will   later develop into one of  the other four cell types.
2.Secondly  B-lymphocytes are responsible for producing   antibodies that will later  recognize and attach themselves to a   specific invader.
3. Once the invading  antigen is marked for destruction by the   B-cell antibody the natural killer  (NK) cells carry out the antigen's   demise. 
4. The process is guided  by the T-lymphocyte's chemical   instructions to the other immune system cells  through lymphokines.   There are numerous sub-types of T-cells including helper  T-cells   T-cytotoxic cells and T-suppressor cells. Most notable T-lymphocytes    initiate direct and shut down the immune response to a specific antigen. 
5. Macrophages can be  thought of as "garbage collectors" that   rid the body of worn-out  cells and other debris. These cells likewise   contain subtypes such as monocytes  which circulate in the bloodstream   looking for foreign material to ingest for  disposal. The macrophage   cell group also includes granulocytes that carry  potent chemicals   capable of destroying some microorganisms by spraying them or  by   ingesting and chemically destroying them.
The  body's immune system is so incredibly diverse that this   thorough process can be  programmed for more that ten million antigens.   Equally fascinating every person  has a unique highly personalized pool   of genetic and acquired immune memories.  Once those memories are in   place the body immediately "remembers" the  specific antigen from   previous invasions and takes decisive action. That's why  varicella   (chicken pox) is a one time illness.
In the  event that T-lymphocytes are either out-numbered or do   not possess the chemical  coding that recognizes an invader cell   infection may spreads unabated. The  results can be and often are   life-threatening.
Five Decades Of Research Bear Results
Nearly  five decades of on-going research and testing have led   to the discovery of the  immune system's workings. While there's more to   be learned immunologists have  now developed highly potent and   chemically "tailored" transfer factors to combat  specific antigens (6 19-22).   Immune-responsive donors are carefully studied to  assure their status   as such. Then through a human donor-to-animal-to-human  recipient   transfer process the antigen-specific immunity is delivered to the    deficient patient. Remarkably those recipients are able to precisely   emulate  the immunity of the donor with significant results.
Until  just a few years ago production of transfer factors was limited to very   minute quantities. Now  through intensive efforts researchers have   developed and refined a process  which mass produces products with transfer factors successfully (19   21 22). Targeted immunotherapy  treatment is now possible for patients   suffering from serious infections that  were once thought to be   untreatable.
In one  study lifelong New York residents with presumably no   prior antigen contact were  given transfer factors of blood leukocytes from   Californians who had delayed immune responses  to coccidioidin.   Rapaport's research showed that successful transfers had  occurred in 28   of 35 recipients of transfer factors and results were seen within as little as  24   hours specifically for coccidioidin (4).
This  led to an important question: Were transfer factors characteristics of   a more random nature  or as the Rapaport study showed were they   consistently specific to a particular  infection? The answer was   confirmed through research conducted by Burger et al  (5) in the mid   1970’s. Burger's unique study again using blood leukocytes  strongly   supported the ability of transfer factors to pass along immunities to specific antigens  in   those receiving treatment. The successful immunity transfer rate was   78%  among 169 recipients tested. So instead of a "shot gun" approach    where the only hope is to conquer the enemy with one big blast, transfer factors could be  used as a sharply focused rifle with the ability to accurately   target and  "gun down" a particular enemy antigen.
Transfer factors immunotherapy has had its share of skeptics mainly because   its exact structure  and mechanism have yet to be completely   understood. Yet significant results  speak for themselves in cases of   herpes simplex Epstein-Barr tuberculosis  cytomegalovirus HIV and many   others. This same phenomenon is reminiscent of the  days when penicillin   was initially viewed with skepticism. Ten years after its  use began no   one knew exactly how penicillin worked even though results were    unmistakably positive.
