Spleen plays an important role in removing old and damaged red blood cells and malaria-infected erythrocytes. When malaria parasites invade the spleen and induce splenomegaly, splenic function tends to be impaired. Thus, the inhibition of splenomegaly is strongly required to protect the spleen. In this study, malaria-induced splenomegaly is inhibited by injecting genistein into a Plasmodium berghei-infected ICR mouse. To explain this phenomenon, the effect of genistein in spleen and liver of malaria-infected mice was evaluated by histological examination. Malaria parasites disrupted splenic architecture. After treating genistein, the disrupted architecture in which red and white pulp regions were clearly separated in recovered to uninfected ones. Changes in biophysical properties of blood were studied by measuring the viscosity of blood collected from malaria-infected and uninfected mice using a microfluidic viscometer. Genistein also had a negligible influence on variation in blood viscosity. The enzymatic activity and expression pattern of proteins were then investigated to explain the genistein effect on malaria-induced splenomegaly. Genistein is a potential drug for splenomegaly in P. berghei-infected mouse.

Spleen traps malaria-infected red blood cells, thereby leading to splenomegaly. Splenomegaly induces impairment in splenic function, i.e., rupture. Therefore, splenomegaly inhibition is required to protect the spleen. In our previous study, genistein was found to have an influence on malaria-induced splenomegaly. However, the effect of genistein in malaria-induced splenomegaly, especially on the function of spleen, has not been fully investigated. In this study, hematoxylin and eosin (H&E) staining images show that genistein partially prevents malaria-induced architectural disruption of spleen. In addition, genistein decreases transgenic Plasmodium parasites accumulation in the spleen. Genistein treatment can protect splenic function from impairment caused by malaria infection. To examine the functions of malaria-infected spleen, we employed single-photon emission computed tomography/computed tomography (SPECT/CT) technology. Red blood cells are specifically radiolabeled with Technetium-99m pertechnetate (99mTcO4-) and trapped inside the spleen. The standardized uptake values (SUVs) in the spleen of infected mice are higher than those of naive and genistein-treated mice. However, genistein reduces the malaria-induced trapping capacity of spleen for heat-damaged radiolabeled RBCs, while exhibiting a protective effect against malaria. Considering these results, we suggested that genistein could be effectively used in combination therapy for malaria-induced splenic impairment.
