The chiropractic immunology connection was strengthened in 1991 when Patricia Brennan, Ph.D. and other researchers found improved immune response following chiropractic treatment. Specifically, the study demonstrated the “phagocytic respiratory burst of polymorphnuclear neutrophils and monocytes were enhanced in adults [who] had been adjusted by chiropractors.” In other words, the cells that act like “Pac-Man”, eating and destroying bad cells, are enhanced through chiropractic care.
