Pathology News and Research

RSS

Pathology is the study and diagnosis of disease through examination of organs, tissues, bodily fluids, and whole bodies (autopsies). The term also encompasses the related scientific study of disease processes, called General pathology. Medical pathology is divided in two main branches, Anatomical pathology and Clinical pathology. Veterinary pathology is concerned with animal disease whereas Phytopathology is the study of plant diseases.

Tolerogenic Dendritic Cells in Gut Prevent Allergic Reactions to Food

The immune system must be able to rapidly target invaders such as viruses while avoiding innocuous stimuli, or allergies may develop.
