invading agent before it can spread too entensively into general circulation. The most importint aspect of T-cell and B-cell lymphocyte operation is that they both have receptors on them which can put-on, modify and redirect their immune activities under the influence of messenger molecules coming from nervous system or endocrine system. In fact these recepioss functions in accordance with lock and key arrangement, the lock being themselves and key to these locks comes in th: form of neurotransmitt:rs, hormones and neuropeptides. These substances have the capacity to turn on the activities of these lymphocytic T-cells and B-cells The types and structures of these messengers and receptor molecules, which must fit each oter to turn on cellular activities, establishes the essential architectural nature of the whole process.
Mind regulates the functions of immune system in three stages. Stage one consists of mind generated thoughts and subsequent neural impulses in the frontal cortex. In the second stage these impulses are filtered through the memory, learning an emotional areas of limbic hypothalamic systein and transduced into immune system (Rossi, 1988 Achterberg, 1985). In the third stage conversion of lymphocytes into T cell and B-cell takes place in thymus and lymph area processipg. Neurotransmitters from autonomic nervous system and he from endocrine glands reaches to the receptors of these lymphocytes thereby enhancing their activites. Nicholas Hall et al (1985) have shown that immunotransmitters are certain specific molecules that are produced predominantly by the cells that comprise the immune system, that transmit specific signals and informations to the neurons and few other cells, thereby providing feedback signal. They also said that it seems that nervous system is capable of altering the course of immunity via ANS and neuroendocrine pathways. EL Rossi (1986) have mentioned that inhibiting or stimulating the hypothalamus results in accountable changes in immune activities. Since the hypothalamus is being governed by higher brain centres, those intercommunications between the immune system and hypothalamus may be liable to conscious mind modulation Further it is proved that lymphocytes bear the receptors for neurotransmitters and hormones, the mind modulating effects of nervous system and endocrine system may be communicaied to immune system too.
