Abstract
Chronic inflammation responses hamper the tissue engineering. immune
system has main function in the regeneration and maintenance of all
tissue, the immune reaction to an implant begins by the innate immune
cells including macrophages which can eventually lead to accept or
reject of the implant. to avoid adverse immune reactions, current
strategies use of immunomodulatory biomaterials rather than inert
materials. The present study aimed to introduce as biomaterial
is capable of modulating macrophage responses. Macrophages cultured on
top of four surfaces then analysis morphological characteristics,
cellular outgrowth and function. In addition, measured the key
cytokine/chemokine markers of macrophage polarization in each sample.
The results of our study pointed out that phage nano-structure can
modulate polarization of macrophages toward anti-inflammatory phenotype
over time. In addition, the combination of well-characterized RGD
peptide motif embedded in bacteriophages can stimulate macrophages
to gain regenerative M2-like phenotype more effectively and it may
introduce an Immuno-modulating biomaterial for tissue engineering
applications.
