Phagotrophic protozoa: A new weapon against pathogens?

Immune suppression is one of the most important factors contributing mortality in systemic diseases like HIV, cancer or diabetes. Moreover, in autoimmune diseases immune suppression itself becomes the only choice of therapy. Finally, fatal bacterial infections occur.

Could pathogens be nutrients for lymphoid cells?

Metabolic and immune systems are very important for a living organism to survive. Since they play crucial roles in maintaining homeostasis, both systems work interdependently. In metabolic disorders like obesity and related diseases, lot of reports have been published about immune system impairment.

Ultrastructural examination of glomerular and tubular changes in renal allografts with acute rejection.

Acute rejection is the most important threat to transplanted kidneys in the early phase after transplantation. With the advances in renal transplant surgery and immunosuppressive therapies, one-year graft survival rates reached 90%, but long-term graft survival did not improve to a similar degree. To prevent acute rejection more effectively and decrease the risk of chronic nephropathy development, the pathogenesis and effects of acute rejection on renal grafts should be further explored.
