How does spleen remove encapsulated bacteria? The spleen contains manymacrophages(part of the reticuloendothelial system), which are immune cells that phagocytose (eat) and destroy bacteria. In particular, these macrophages are activated when bacteria are bound by IgG antibodies (IgG1 or IgG3) or...
Using the mouse as a model system, we have recently shown that myeloid-derived suppressor cells (MDSCs) are more abundant in the spleens of neonatal and infant mice and contribute to elevated IL-27 levels in young mice. Functional studies demonstrate that these MDSCs express active nitric ...
How does the spleen help the immune system? How do interferons protect against viral infection in healthy cells? What is the difference in how a virus and bacteria replicate and affect cells of the body? How does lack of sleep affect the immune system? What is the immune system? What does...
the gastrointestinal tract and competition from other bacteria resulted in a significant decrease in the activity of probiotics. In addition, the rapid gastrointestinal (GI) transit time also makes it difficult for probiotics to remain and colonize in the intestine [16,17,18]. These factors make i...
A similar trend was observed for both bacteria in SIF (Fig. 2B). The strong electrostatic interactions and hydrogen bonding between the phosphate groups in SP and the amino groups in CS may prevent the diffusion of H+ ions and bile salts into the cell wall and membrane. Thus, (CS/SP)2...
lesions in the vascular endothelium, accumulation of ascitic fluid in peritoneal cavity, surface (in the base of fins, opercula-bucal region) and internal hemorrhages (in the swim bladder, intestine, liver, spleen and kidney) and also necrosis in the liver and spleen [1,[3], [4], [5]...
Hematoxylin & Eosin, Magnification = ×400 infected mice in the chronic and acute phase, respectively which both results dedicated that the NPs could decrease bacteria colonies significantly from spleen and liver [19, 24]. In overall, according to the mentioned studies gen- tamicin has a ...
The results suggest that liposome-encapsulated antimicrobial agents may possess a therapeutic advantage in the treatment of diseases caused by facultative intracellular bacteria since this manipulation favors delivery of the entrapped antibiotic to intracellular sites occupied by S. typhimurium. 展开 ...

This study investigated whether the spleen volume could predict the prognosis of patients with bacteremia caused by encapsulated organisms.#This was a single-center, retrospective observational study at Tokyo Medical University Hospital. Twenty patients with encapsulated bacteria (Streptococcus pneumoniae,...
