OBJECTIVE To evaluate features of general immune function, in particular the restoration of the humoral immune response to pneumococcal capsular polysaccharides, in humans undergoing a spleen autotransplantation after splenectomy because of trauma. SUMMARY BACKGROUND DATA After splenectomy, patients have an increased risk of overwhelming infection or sepsis involving encapsulated bacteria such as pneumococci. The value of human spleen autotransplantation after splenectomy because of trauma… 
Autotransplant of spleen tissue in children with schistosomiasis: evaluation of splenic function after splenosis.
TLDR
Splenosis was efficient in maintaining the filtration splenic function in more than 90% and produced tuftsin inside the range of normality and provided the immunologic splenic response to pneumococcal vaccination in 65% of the patients of this series.
Splenic regeneration following splenectomy and impact on sepsis: a clinical review
TLDR
The role of splenosis and spleen autotransplantation in patients who suffer splenic trauma and their possible protective role on post‐splenectomy sepsis is studied.
After chemotherapy, functional humoral response capacity is restored before complete restoration of lymphoid compartments
TLDR
According to this study, the presence of only few marginal zone B cells is sufficient to evoke a rise in antibody titres and although antibody titre increases are low, even small rises are most likely clinically relevant.
Recurrent penicillin-resistant pneumococcal sepsis after matched unrelated donor (MUD) transplantation for refractory T cell lymphoma
TLDR
This case illustrates that the choice of prophylactic regimen and the treatment of sepsis in immunocompromised patients remain difficult and challenging issues.
Antibody Response of Autogenous Splenic Tissue Implanted in the Abdominal Cavity of Mice
TLDR
The T cell-dependent antibody response in implanted splenic tissues is as efficient as in the intact spleen, with no difference between the graft sites studied.
Distribution of peripheral blood cells in mice after splenectomy or autotransplantation
TLDR
In conclusion, spleen autotransplantation has some beneficial effects, including clearing erythrocytes and preserving the phagocytic activity of neutrophils in peripheral blood.
Single segment of spleen autotransplantation, after splenectomy for trauma, can restore splenic functions
TLDR
It is suggested that splenic autotransplantation is able to restore an adequate hemocatheretic activity as well as recover the immunological deficit after splenectomy.
Splenic tissue autotransplantation in rabbits: no restoration of host defense
TLDR
The low quantity and poor quality of the regenerated splenic tissue contribute to the inferior immunoprotective ability of animals autotransplanted with one-third of the original spleen, suggesting that the regeneration spleen cannot compensate for the immunological function of theOriginal one, especially host resistance to infection.
Bacterial phagocytosis by macrophage of autogenous splenic implant.
TLDR
The present results suggest that autogenous splenic implants in the greater omentum of the rat acquire the macro- and microscopic architecture of a normal spleen, with reduced dimensions, and preserve bacterial phagocyte function.

Serum antibody responses to pneumococcal vaccine after splenic autotransplantation.
TLDR
The combination of splenic autotransplantation and pneumococcal vaccination may confer more protection than either modality alone in individuals who must undergo splenectomy.
Splenic Autotransplantation and the Immune System Adequate Testing Required for Evaluation of Effect
TLDR
It appears that postsplenectomy vaccination is more successful when recently developed protein-conjugated polysaccharide vaccines are used, and testing of the function of spleen autotransplants is not adequate, it is suggested that new tests should be developed, employing appropriate poly Saccharide antigens.
Lack of effect of splenic regrowth on the reduced antibody responses to pneumococcal polysaccharides in splenectomized patients.
TLDR
In vivo evidence indicating that ectopic splenic tissue in humans does not normalize the altered antibody responses observed following splenectomy is shown, indicating that in adult humans the spleen is important in the maintenance of normal humoral immune responses.
Protection against pneumococcal sepsis in splenectomized rats by implantation of splenic tissue into an omental pouch.
TLDR
Rats bearing reimplanted splenic tissue in an omental pouch were protected against pneumococcal peritonitis and had a significant difference in survival rate following bacterial inoculation.
Immaturity of the human splenic marginal zone in infancy. Possible contribution to the deficient infant immune response.
TLDR
There is a remarkable coincidence between the first appearance of MZ B cells with adult features, and the time of acquisition of the ability to mount an immune response to polysaccharides, including encapsulated bacteria.
Immunoregulatory role of the spleen in antibody responses to pneumococcal polysaccharide antigens
TLDR
It is shown that, even in the presence of extrasplenic antibody synthesis, the spleen is required for early antibody production, the timing of which is critical for the effective clearance of bacteria.
Immunological function in post-traumatic splenosis.
TLDR
A 28-year-old male medical student underwent splenectomy at 8 years of age due to traumatic rupture of the spleen sustained in a motor vehicle accident and, at the time of surgery, over 100 splenic nodules were found embedded throughout the patient's omentum, small bowel, and mesentery.
Does naturally acquired IgG antibody to cell wall polysaccharide protect human subjects against pneumococcal infection?
TLDR
The data suggest that naturally present anti-CWPS IgG does not protect against the evolution of acute pneumococcal infection from colonization to acute purulent bronchitis, fromBronchitis to pneumonia, or from pneumonia to bacteremia.
Fc‐receptor function after human splenic autotransplantation
TLDR
Although the Fc‐receptor test showed delayed and monoexponential blood clearance in all patients after splenectomy, there were no significant differences between the patient groups.
