A number of life-threatening diseases, such as kidney failure, diabetes, and certain kinds of coronary heart disease, can be cured by organ transplantation. However, despite decades of research, graft rejection remains a very real threat to the organ transplant recipient. In attempting to develop methods that interfere with the graft rejection process, scientists have uncovered a remarkably complex system of cellular interactions that allows the total destruction of a transplanted organ while leaving the recipient's own organs untouched. This ability to distinguish self from non-self is achieved through intercellular communication involving cell-to-cell contact and the release of a number of …

Man's skin response to the mosquito bite exhibits great individual variability. The everyday immediate reaction consists o f a red, or erythematous wheal that lasts only one or two hours. Twenty to 24 hours after the mosquito bite, a delayed reaction of erythema, swelling, and itching may also occur. An individual may exhibit an immediate reaction, delayed reaction, both reactions, or neither reaction. Studies suggest that sensitization to mosquito saliva may be responsible for the inflammatory response. This hypothesis is supported by histologic studies which demonstrate striking infiltration of inflammatory cells at the site of mosquito bites. Severe local reactions …
