Isolated mucins and different microorganisms, and methods of use
A method of altering intercellular interactions between a combination of microorganisms includes contacting a combination of different species of microorganisms with at least one mucin. Isolated compositions include a combination of microorganisms and at least one mucin. One microorganism of the combination inhibits cell growth or promotes cell death of at least one other microorganism of a different species in the combination. The combination of microorganisms with the mucin results an increase in cell growth or a reduction in cell death, respectively, of the at least one other microorganism.
1. A method of altering intercellular interaction between different species of microorganisms that intercellularly inhibit cell growth or intercellularly promote cell death, or both, comprising the steps of:
a) combining at least one isolated human mucin with a microorganism to thereby form a combination, the microorganism including at least one member selected from the group consisting of a bacterium, an archaeon and a fungus;
b) dessicating the combination of the microorganism and at least one isolated human mucin to thereby form a dessicated combination; and
c) combining the dessicated combination with at least one microorganism of a species that is different from the microorganism in the dessicated combination, thereby altering at least one of the intercellular inhibition of cell growth and the intercellular promotion of cell death of the at least one microorganism of the species that is different from the microorganism in the dessicated combination, the intercellular inhibition of cell growth or intercellular promotion of cell death, or both, that is altered is that of at least one microorganism selected from the group consisting of a bacterium, an archaeon and a fungus.
2. The method of claim 1 , wherein the intercellular interaction that is altered is inhibition of cell growth.
3. The method of claim 1 , wherein the intercellular interaction that is altered is promotion of cell death.
4. The method of claim 1 , wherein the isolated human mucin is at least one member selected from the group consisting of a gastric mucin, a salivary gland mucin, and a respiratory tract mucin.
5. The method of claim 1 , wherein the dessicated combination of the microorganism and at least one isolated human mucin is attached to a biocompatible substrate.
6. The method of claim 5 , wherein the biocompatible substrate is a polymer bead.
7. The method of claim 5 , wherein the biocompatible substrate is a liposome.
8. A method of altering intercellular interaction between different species of microorganisms that intercellularly inhibit cell growth or intercellularly promote cell death, or both, comprising the steps of:
a) combining at least one mucin with a microorganism to thereby form a combination, the microorganism including at least one member selected from the group consisting of a bacterium, an archaeon and a fungus;
b) dessicating the combination of the microorganism and at least one mucin to thereby form a dessicated combination; and
c) combining the dessicated combination with at least one microorganism of a species that is different from the microorganism in the dessicated combination, thereby altering at least one of the intercellular inhibition of cell growth and the intercellular promotion of cell death of the at least one microorganism of the species that is different from the microorganism in the dessicated combination, the intercellular inhibition of cell growth or intercellular promotion of cell death, or both, that is altered is that of at least one microorganism selected from the group consisting of a bacterium, an archaeon and a fungus, wherein the dessicated combination of the microorganism and at least one mucin is attached to a biocompatible substrate, wherein the biocompatible substrate is a polymer bead.
9. The method of claim 8 , wherein the at least one mucin is an isolated mucin.
10. The method of claim 9 , wherein the isolated mucin is an isolated non-human mucin.
11. The method of claim 9 , wherein the isolated mucin is an isolated human mucin.
12. A method of altering intercellular interaction between different species of microorganisms that intercellularly inhibit cell growth or intercellularly promote cell death, or both, comprising the steps of:
a) combining at least one mucin with a microorganism to thereby form a combination, the microorganism including at least one member selected from the group consisting of a bacterium, an archaeon and a fungus;
b) dessicating the combination of the microorganism and at least one mucin to thereby form a dessicated combination; and
c) combining the dessicated combination with at least one microorganism of a species that is different from the microorganism in the dessicated combination, thereby altering at least one of the intercellular inhibition of cell growth and the intercellular promotion of cell death of the at least one microorganism of the species that is different from the microorganism in the dessicated combination, the intercellular inhibition of cell growth or intercellular promotion of cell death, or both, that is altered is that of at least one microorganism selected from the group consisting of a bacterium, an archaeon and a fungus, wherein the dessicated combination of the microorganism and at least one mucin is attached to a biocompatible substrate, wherein the biocompatible substrate is a liposome.
13. The method of claim 12 , wherein the at least one mucin is an isolated mucin.
14. The method of claim 13 , wherein the isolated mucin is an isolated non-human mucin.
15. The method of claim 13 , wherein the isolated mucin is an isolated human mucin.
