Abstract
The development of molecules with immune stimulatory properties is crucial for cancer immunotherapy. In this work, we combined two peptide-based molecules, tuftsin (TKPR) and Nap-GDFDFDY, to develop a novel self-assembling molecule Nap-GDFDFDYTKPR (Comp.3), which has strong CD8+ T cell stimulatory properties. Comp.3 could self-assemble into nanofibers and hydrogels, which significantly improved the stability of tuftsin against enzyme digestion. The nanofibers of Comp.3 enhanced the phagocytic activity of macrophages, promoted the maturation of DCs, and stimulated the expression of cytokines. In addition, it demonstrated an excellent anti-tumor efficacy in vivo by eliciting a strong CD8+ T immune response. Taken together, our observations revealed a powerful immune stimulating nanomaterial that is a promising compound for cancer immunotherapy.

Abstract
The series of 16 novel amino acid and peptide mycophenolic acid (MPA) derivatives was obtained as potential antibacterial agents. Coupling of MPA with respective amines was optimized with condensing reagents such as EDCI/DMAP and T3P/TEA. Amino acid analogs were received both as methyl esters and also with the free carboxylic group. The biological activity of the products was tested on five references bacterial strains: Klebsiella pneumoniae ATCC 700603 (ESBL), Escherichia coli ATCC 8739, Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus MRSA ATCC 43300, Staphylococcus aureus MSSA ATCC 25923. Peptide derivatives proved to be the most versatile ones, their MIC values relative to most strains was lower than MPA alone. It has been noted that the activity of amino acid derivatives depends on the configuration at the chiral center in the amino acid unit and methyl esters indicated better antimicrobial activity than analogs with free carboxylic group.

Up-regulation of MDP and tuftsin gene expression in Th1 and Th17 cells as an adjuvant for an oral Lactobacillus casei vaccine against anti-transmissible gastroenteritis virus. Appl Microbiol Biotechnol 2014; 98:8301-12.

Abstract
The role of muramyl dipeptide (MDP) and tuftsin in oral immune adjustment remains unclear, particularly in a Lactobacillus casei (L. casei) vaccine. To address this, we investigated the effects of different repetitive peptides expressed by L. casei, specifically the MDP and tuftsin fusion protein (MT) repeated 20 and 40 times (20MT and 40MT), in mice also expressing the D antigenic site of the spike (S) protein of transmissible gastroenteritis virus (TGEV) on intestinal and systemic immune responses and confirmed the immunoregulation of these peptides. Treatment of mice with a different vaccine consisting of L. casei expressing MDP and tuftsin stimulated humoral and cellular immune responses. Both 20MT and 40MT induced an increase in IgG and IgA levels against TGEV, as determined using enzyme-linked immunosorbent assay. Increased IgG and IgA resulted in the activation of TGEV-neutralising antibody activity in vitro. In addition, 20MT and 40MT stimulated the differentiation of innate immune cells, including T helper cell subclasses and regulatory T (Treg) cells, which induced robust T helper type 1 and T helper type 17 (Th17) responses and reduced Treg T cell immune responses in the 20MT and 40MT groups, respectively. Notably, treatment of mice with L. casei expressing 20MT and 40MT enhanced the anti-TGEV antibody immune responses of both the humoral and mucosal immune systems. These findings suggest that L. casei expressing MDP and tuftsin possesses substantial immunopotentiating properties, as it can induce humoral and T cell-mediated immune responses upon oral administration, and it may be useful in oral vaccines against TGEV challenge.

Abstract
Targeted therapy is a potentially useful approach for antileukemic therapy, in particular eliminating minimal residual disease (MRD) to prevent tumor relapse. In this study, the immunomodulator (MDP-Ab) was constructed by coupling anti-CD10 monoclonal antibody (MAb) and muramyl dipeptide (MDP) using heterobifunctional reagent SPDP and the activity of MDP-Ab through dendritic cells (DCs)-based immunotherapy was identified in targeted therapy for leukemia. Results showed that the molecular ratio of purified MDP-Ab immunomodulator was about 2:1 according to electrospray ionization mass spectrometry (ESI-MS). The immunoreactivity and specificity of the new immunomodulator on CD10 antigen was identical to that of unconjugated native anti-CD10 MAb. The immunomodulatory effect of MDP-Ab immunoconjugate on peripheral blood dendritic cells (PBDCs) from children with acute lymphoblastic leukemia (ALL) exhibited upregulated expression of HLA-DR, co-stimulatory marker (CD80 and CD86) and maturity marker (CD83), increased cytokine secretion (interleukin-12, IL-12) and enhanced autostimulatory activity. These results in vitro suggested that MDP-Ab immunoconjugate may be a suitable candidate for targeting trials and support the further development of vaccination with the new immunomodulator-triggered DCs as a post-remission treatment to prevent relapse in ALL children.

Abstract
Structurally related peptidoglycan monomer (PGM) and muramyl dipeptide (MDP) differ in several aspects of biological activity but have in common immunostimulating properties. Comparative study of the effects of these adjuvants on humoral IgG immune response specific for protein antigen ovalbumin (OVA) was carried out in two inbred mouse strains, CBA and NIH/OlaHsd, and their ability to modulate the bias of immune response towards Th1/Th2 was evaluated. MDP had better adjuvant activity at some points than PGM, whereas both adjuvants stimulated Th2-biased immune response specific for OVA. In comparison to Complete Freund's adjuvant (CFA), as a golden standard of adjuvant action, both PGM and MDP exhibited considerably lower activity. Addition of PGM to Incomplete Freund's adjuvant (IFA) on humoral immune response was studied also, and the effect of such adjuvant formulation was compared to the effect of CFA. While CFA induced the switch towards Th1-biased immune response, the addition of PGM into IFA did have no impact on modulating the immune response towards more pronounced Th2-type of immune response, defined by IFA itself.

Abstract
Pharmacological manipulation of the balance between pro- and anti-inflammatory mediators emerges as a key aspect of a successful treatment of sepsis. A murine model of septic shock was developed and chosen conjugates (1a, 1b, 8a, 8c) and analogs (T2) of muramyl dipeptide and tuftsin were tested in this model as prospective anti-bacterial drugs or adjuvants. The phagocytic activity of monocytes/macrophages was determined (flow cytometry, bacterial clearance from vital organs). To evaluate cytokines levels (TNFalpha, IFNgamma, IL6, IL10) we used real-time PCR. The most promising immunomodulatory properties were displayed by the analogue T2 and two conjugates: 8a, 8c.

Abstract
Peptide-based therapies offer the potential for non-genotoxic, genotype-specific alternatives, or adjuvants, to the current range of traditional cancer treatments. Such a patient-tailored cancer-cell-directed therapeutic approach should have fewer side effects and could well be more effective than the current drug- or combination-based regimens. Here, we review the potential of novel natural anticancer peptides such as necrotic peptides, apoptotic peptides, function-blocking peptides, antiangiogenic peptides and immunostimulatory peptides in the context of their ability to induce tumor regression. We focus on the therapeutic prospects of anticancer peptides and their possible application in tumor therapy.
