AI Technical Summary

Benefits of technology

The present invention provides a composition of plasma-derived IgM that can be used for the treatment of sepsis and immune complications caused by infections. The method involves administering a composition of IgM to patients in need of treatment. The technical effect is the use of a natural substance, plasma-derived IgM, for the treatment of sepsis and other immune complications caused by infections.

Problems solved by technology

Microbial species can become highly deleterious to the infected patient, if that individual cannot clear the infection.
These septic infections have a poor outcome for patients.
Septic conditions and other complications of microbial infections are often associated with an over-stimulation of the immune system, and are often impossible to control due to their exaggerated magnitude and quick evolution.

of the Influence of IgM in the Proliferation of Peripheral Blood Mononuclear Cells

[0113]Since IgM showed clear effects on the NF-κB pro-inflammatory pathway, it was also assessed whether purified IgM had a more general effect on immune functions. Proliferation of blood lymphocytes, particularly of T-cells stimulated by antigen, is one of the most basic pro-inflammatory immune responses.

[0114]Phorbol 12-myristate 13-acetate (PMA) and ionomycin, a very general proliferation stimulant, were used to induce proliferation of peripheral blood mononuclear cells, more precisely blood T-lymphocytes or T-cells.

[0115]Human peripheral blood mononuclear cells were cultured in RPMI with 10% heat inactivated human serum. For proliferation assays, 3×105 cells were seeded in each well of a 96-well plate using culture media.

[0116]T-cells were treated with 10 ng / mL PMA and 0.5 μM ionomycin for 3 days. In case IgM was used cells were treated or co-treated with purified IgM (at a final concentration of a...

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to United States Provisional Patent Application No. 62 / 201,917, filed Aug. 6, 2015, the contents of all of which are specifically incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to the treatment or prevention of immune symptoms or conditions by administering compositions comprising IgM.BACKGROUND OF THE INVENTION[0003]Microbial species can become highly deleterious to the infected patient, if that individual cannot clear the infection. Infections can also become septic, spreading from an infected organ into the blood stream. These septic infections have a poor outcome for patients.[0004]It is well characterized that plasma-derived IgM can bind to and prevent endotoxin-mediated toxicity towards a patient. This is attributed to the inherent ability or preference of IgM to bind glycans thereby preventing their effects. These toxic effects of endotoxins are typically ...
