Abstract
Carbonic anhydrase owing to its potential as an industrial biocatalyst for carbon dioxide sequestration from flue gas has attracted considerable attention in solving global warming problems. A large body of research has been conducted to increase the thermal stability of carbonic anhydrase from different sources against the harsh operational conditions of CO2 capture systems. In contrast to cost-intensive protein engineering methods, solvation with aqueous-organic binary mixtures offers a convenient and economical alternative strategy for retention of protein structure and stability. This study aimed to examine the stabilizing effect of methyl diethanolamine (MDEA) as a component of an aqueous-organic solvent mixture on human carbonic anhydrase II (HCA II) at extreme temperatures. Computational and also spectroscopic examinations were employed for tracking conformational changes and stability evaluation of HCA II in 50:50 (vol %) water: MDEA binary mixture at high temperature. Molecular dynamic (MD) simulation studies predicted the high thermal stability of HCA II in the presence of MDEA. UV absorbance spectra confirmed the thermo-stabilizing effect of the binary solvent mixture on HCA II. While the enzymatic activity of HCA II at 25 °C in the presence of 10, 25, and 50 (vol%) of MDEA was substantially increased, no obvious effect on retention of HCA II activity in the water-MDEA binary solvent mixture at 85 °C was seen. It is shown that the solvation of HCA II in the presence of MDEA could result in the prevention of aggregate formation in high temperatures but not functional stability.Communicated by Ramaswamy H.

Abstract
BACKGROUND Colorectal cancer is one of the widespread and lethal types of malignancies. Recently, antineoplastic attributes of probiotics have attracted lots of attention. Here, we investigated anti-proliferative potential of the non-pathogenic strains Lactobacillus plantarum ATCC 14,917 and Lactobacillus rhamnosus ATCC 7469 on human colorectal adenocarcinoma-originated Caco-2 cells. METHODS AND RESULTS Caco-2 and HUVEC control cells were treated with ethyl acetate extracts of the two Lactobacillus strains to assess cell viability by MTT assay. Annexin/PI staining flow cytometry, and caspase-3, -8 and - 9 activity assays were performed to determine the type of cell death induced in extract-treated cells. Expression levels of apoptosis-related genes were evaluated by RT-PCR. Extracts from both L. plantarum and L. rhamnosus specifically targeted the Caco-2 cells and not HUVEC controls, and significantly affected the viability of the colon cancer cell line in a time- and dose-dependent manner. This effect was shown to occur through activation of the intrinsic apoptosis pathway, as indicated by the increased caspase-3 and - 9 activities. While there are limited and conflicting data about the mechanisms underlying the specific antineoplastic attributes of Lactobacillus strains, we clarified the overall induced mechanism. The Lactobacillus extracts specifically down-regulated the expression of the anti-apoptotic bcl-2 and bcl-xl, and simultaneously up-regulated the pro-apoptotic bak, bad, and bax genes in treated Caco-2 cells. CONCLUSIONS Ethyl acetate extracts of L. plantarum and L. rhamnosus strains could be considered as targeted anti-cancer treatments specifically inducing the intrinsic apoptosis pathway in colorectal tumor cells.

Abstract
Due to the high affinity for binding to target molecules and also other unique attributes, affibodies have a great potential to be used in immunotherapeutic and diagnostic approaches. However, the possibility of undesirable immune response is still a great concern. In the current study, we investigated the possible antigenicity, allergenicity and cytotoxicity of the HER2-targeting affibody ZHER2. The binding affinity of potential epitopes of the affibody to murine major histocompatibility complex (MHC) molecules was investigated by immunoinformatics tools and docking approaches. The possible interaction of ZHER2 with human leukocyte antigens HLA-DP, HLA-DM, HLA-DQ and HLA-DR was also studied by protein-protein docking. Additionally, the synthesized affibody gene was expressed and the protein was purified for boosted immunization of Balb/c mice. Induced secretion of IFN-γ, IL-2, IL-4 and IL-10, and total serum IgG were assessed in the immunized mice. Furthermore, MTT cell viability test was performed to evaluate the cytotoxicity of ZHER2 in splenocytes of the treated mice. In silico analyses showed the possible induction of the immune response by ZHER2. While the affibody could elicit the secretion of cellular immune cytokines, it could not induce a significant humoral response in the treated mice and did not show any cytotoxic effects on the exposed splenocytes. These findings explain the practicability of ZHER2 for therapeutic and in vivo diagnostic usages, though its ubiquitous application may need more studies.

Abstract
Hyaluronidase (HAase) from bovine testes (BTH) has long been used in broad pharmaceutical areas, while it is associated with drawbacks in aspects of solubility, immunogenicity and pharmacokinetics. These issues can be addressed by gaining structural insights and designing rational modifications to the enzyme structure, as proposed in this study. A 3D structural model was built for HAase and underwent 40 ns of molecular dynamic simulation to examine its thermostability under normal, melting, and extreme conditions. The enzyme activity of BTH was measured against temperature and pH by kinetic assays. The interaction of bovine HAase with HA and chondroitin was defined by molecular docking. Furthermore, immunogenic properties of the enzyme were explored by immunoinformatics. Thermal effects on bovine HAase structural model and the HAase interactions with its substrates were described. We identified some B- and T-cell epitopes and showed that the protein could be recognized by human immune receptor molecules. Epitope masking by adding polyethylene glycol (PEG) to amine groups of residues presenting on the surface of the protein structure was adopted as a surface modification to enhance pharmacological properties of BTH. Assays showed that PEGylated BTH had higher thermostability and similar activity compared to the native enzyme.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) expresses a multifunctional papain-like proteinase (PLpro), which mediates the processing of the viral replicase polyprotein. Inhibition of PLpro has been shown to suppress the viral replication. This study aimed to explore new anti-PLpro candidates by applying virtual screening based on GRL0617, a known PLpro inhibitor of SARS coronavirus (SARS-CoV). The three-dimensional (3D) structure of SARS-CoV-2 PLpro was built by homology modeling, using SARS-CoV PLpro as the template. The model was refined and studied through molecular dynamic simulation. AutoDock Vina was then used to perform virtual screening where 50 chemicals with at least 65% similarity to GRL0617 were docked with the optimized SARS-CoV-2 PLpro. In this screening, 5-(aminomethyl)-2-methyl-N-[(1R)-1-naphthalen-1-ylethyl]benzamide outperformed GRL0617 in terms of binding affinity (-9.7 kcal/mol). Furthermore, 2-(4-fluorobenzyl)-5-nitro-1H-isoindole-1,3(2H)-dione (previously introduced as an inhibitor of cyclooxygenase-2), 3-nitro-N-[(1r)-1-phenylethyl]-5-(trifluoromethyl)benzamide (inhibitor against Mycobacterium tuberculosis), as well as the recently introduced SARS-CoV-2 PLpro inhibitor 5-acetamido-2-methyl-N-[(1S)-1-naphthalen-1-ylethyl]benzamide showed promising affinity for the viral proteinase. All of the identified compounds demonstrated an acceptable pharmacokinetic profile. In conclusion, our findings represent rediscovery of analgesic, anti-inflammatory, antibacterial, or antiviral drugs as promising pharmaceutical candidates against the ongoing coronavirus.

Abstract
Background & Objective: Overexpression of human epidermal growth factor receptor 2 (HER2) causes cell transformation and development of various types of malignancies. Idarubicin is an effective anti-neoplastic drug but its specific delivery to the targeted cells is still a great challenge. Affibody as a cost-effective peptide molecule with low molecular weight has a high affinity for HER2 receptors. Breast and ovarian cancers as wide speared types of malignancies are associated with high expression of HER2. In the current study, we assessed the cytotoxic effects of idarubicin-ZHER2 affibody conjugate on the positive-HER2 cancer cell lines. Methods: The cytotoxic effects of constructed idarubicin-ZHER2 affibody conjugate on the SK-BR-3, SK-OV-3, and MCF-7 cells with various levels of HER2 expression were evaluated by MTT assay following 48 hours of incubation. Results: Idarubicin showed a potent and dose-dependent cytotoxic effect against all treated cell lines while the SK-OV-3 cells were significantly more sensitive. The dimeric form of the ZHER2 affibody molecule showed a mild effect on the cell viability of all treated cells at its optimum concentration. The constructed Idarubicin-ZHER2 affibody conjugate decreased the viability of SK-OV-3 cells at its optimal concentration, more efficiently and specifically than other treated cells. Conclusion: The ZHER2-affibody conjugate of idarubicin has a more specific cytotoxic effect compared with idarubicin alone against HER2-overexpressing ovarian cancerous cells. It appears the ZHER2-affibody conjugate of idarubicin has great potential to be implicated as an innovative anti-cancer agent in future clinical trials in patients with HER2-overexpressing ovarian cancer.

Abstract
Amygdalin induces apoptotic death in several carcinoma cells. Affibody is an engineered protein with a high affinity for human epidermal receptor 2 (HER2). We assessed the cytotoxic effects of the amygdalin-ZHER2 affibody conjugate on two breast carcinoma cell lines. The ZHER2 affibody gene was synthesized and transferred into E. coli BL21 as an expression host. After purification, the ZHER2 affibody was conjugated to amygdalin. The cytotoxic effects of amygdalin and its ZHER2 affibody conjugate on the SK-BR-3, with overexpression of HER2, and MCF-7 cells were evaluated by MTT assay. The effects of amygdalin and its conjugate on apoptotic death and expression of pro-apoptotic Bax and anti-apoptotic Bcl-2 proteins were measured. Amygdalin individually showed a potent cytotoxic effect against both MCF-7 (IC50 = 14.2 mg ml-1) and SK-BR-3 cells (IC50 = 13.7 mg ml-1). However, the amygdalin-ZHER2 affibody conjugate had a more cytotoxic effect on SK-BR-3 (IC50 = 8.27 mg ml-1) than MCF-7 cells (IC50 = 19.8 mg ml-1). Amygdalin had a significant apoptotic effect on both cell lines and the effect of its conjugate on SK-BR-3 cells was significantly more potent than MCF-7 cells. Amygdalin increased Bax and decreased Bcl-2 expression in both cell lines. However, the effect of its conjugate on the Bax and Bcl-2 expression in SK-BR-3 was more potent than MCF-7 cells. In conclusion, the amygdalin-ZHER2 affibody conjugate may be considered as a valuable candidate for specific treatment of breast cancer patients with overexpression of HER2. However, further in vivo studies are required to explain the antitumoral effects of constructed amygdalin-ZHER2 affibody conjugate.

Abstract
BACKGROUND Expression of human epidermal growth factor receptor type 2 (HER2) in head and neck squamous cell carcinoma (HNSCC) cell line HN5 can be employed with great opportunities of success for specific targeting of anti-cancer chemotherapeutic agents. OBJECTIVE In the current study, HER2-specific affibody molecule, ZHER2:342 (an engineered protein with great affinity for HER2 receptors) was selected for conjugation to idarubicin (an anti-neoplastic antibiotic). METHOD ZHER2:342 affibody gene with one added cysteine code at the its 5' end was synthesized de novo and then inserted into pET302 plasmid and transferred to E. Coli BL21 hosting system. After induction of protein expression, the recombinant ZHER2 affibody molecules were purified using Ni- NTA resin and purity was analyzed through SDS-PAGE. Affinity-purified affibody molecules were conjugated to idarubicin through a heterobifunctional crosslinker, sulfosuccinimidyl 4-(Nmaleimidomethyl) cyclohexane-1-carboxylate (Sulfo-SMCC). Specific toxicity of idarubicin-ZHER2 affibody conjugate against two HER2-positive cells, HN5 and MCF-7 was assessed through MTT assay after an exposure time of 48 hours with different concentrations of conjugate. RESULTS Idarubicin in the non-conjugated form showed potent toxic effects against both cell lines, while HN5 cells were significantly more sensitive compared to MCF-7 cells. Dimeric ZHER2 affibody showed a mild decreasing effect on growth of both HN5 and MCF-7 cells at optimum concentration. Idarubicin-ZHER2 affibody conjugate at an optimum concentration reduced viability of HN5 cell line more efficiently compared to MCF-7 cell line. CONCLUSION In conclusion, idarubicin-ZHER2 affibody conjugate in optimum concentrations can be used for specific targeting and killing of HN5 cells.

Abstract
Targeting of cancerous cells with a high level of human epidermal growth factor receptor 2 (HER2) expressions by drug immunoconjugates is a new approach for specific delivery of chemotherapeutic agents. Our previous work indicated that idarubicin-ZHER2 affibody conjugate has a great potential for the treatment of HER2-overexpressing malignant cell lines but possible induced immune response against constructed conjugate was not addressed. In the current study, the possibility of induction of humoral and cellular immune responses against idarubicin-ZHER2 affibody conjugate in BALB/c mice was investigated. For assessment of the induced immune response, prepared and qualified idarubicin-ZHER2 affibody conjugate was administrated intravenously to BALB/c mice and the induced cellular immune response was evaluated by measuring secretion levels of interferon gamma (IFN-γ) and interleukin 10 (IL-10) cytokines by the splenocytes. Humoral response of treated mice was also assessed by measuring total immunoglobulin G (IgG) titer in mice sera. The obtained results showed that idarubicin-ZHER2 affibody conjugate at any examined concentrations could not induce secretion of IFN-γ as a pro-inflammatory cytokine. A mild increase in the level of regulatory IL-10 cytokine was seen in the treated mice although no dose dependency in the level of IL-10 production was observed. Furthermore, results showed that idarubicin-ZHER2 conjugate could not induce IgG production in the treated mice. Based on these findings, the idarubicin-ZHER2 conjugate can be considered as a candidate for the development of new therapeutics against HER2-overexpressing cancers although further in vivo studies are needed.

Abstract
Background:
Chemotherapy is a routine approach in treatment of patients with cancer,
while side effects of chemotherapeutic drugs are inevitable. To minimize side effects, specific targeting
of neoplastic cells is a promising strategy in cancer therapy. Sodium arsenite is a metalloid
toxin with anti-neoplastic properties, but low selectivity and carcinogenic activity have limited its
clinical usage.
Methods:
Targeting of HER2-overexpressing (SK-BR-3) and HER2-low expressing (MCF-7) cancerous
breast cell lines by two different liposomal forms of sodium arsenite (bare liposome and
trastuzumab-conjugated liposome) was investigated in the current study. Levels of HER2 expression
in the above mentioned cell lines were confirmed by western blotting. Size and morphology of
the constructed liposomes were characterized by atomic force microscopy (AFM) and dynamic light
scattering (DLS). Viability of the cells after treatment was assessed using MTT assay.
Results:
Sodium arsenite in the free and liposomal forms showed growth inhibitory effects against
both SK-BR-3 and MCF-7 cell lines in an examined concentration range of 1-20 µM, although this
effect was more significant in SK-BR-3 cell line. Loading of sodium arsenite in anti-HER2 immunoliposomes
significantly enhanced its cytotoxicity while the specificity was also improved. By
encapsulation of sodium arsenite in anti-HER2 immunoliposomes, its efficacy in ablation of SKBR-
3 cells was increased about 1.4-fold compared to the free or liposomal forms.
Conclusion:
In conclusion, targeted delivery of sodium arsenite using anti-HER2 immunoliposomes
can be considered as an alternative strategy for specific treatment of HER2-positive
breast cancers.

Abstract
AIM In the present study, a protein-protein interaction network construction is conducted for IBD. BACKGROUND Inflammatory bowel diseases as serious chronic gastrointestinal disorders attracted many molecular investigations. Diverse molecular information is present for IBD. However, these molecular findings are not highlighted based on interactome analysis. On the other hand, PPI network analysis is a powerful method for study of molecular interactions in the protein level that provide useful information for highlighting the desired key proteins. METHODS Cytoscape is the used software with its plug-ins for detailed analysis. Two centrality parameters including degree and betweenness are determined and the crucial proteins based on these parameters are introduced. RESULTS The 75 proteins among 100 initial proteins are included in the network of IBD. Seventy-five nodes and 260 edges constructed the network as a scale free network. The findings indicate that there are seven hub-bottleneck proteins in the IBD network. CONCLUSION More examination revealed the essential roles of these key proteins in the integrity of the network. Finally, the indicator panel including NFKB1, CD40, TNFA, TYK2, NOD2, IL23R, and STAT3 is presented as a possible molecular index for IBD.

Abstract
Background Metals can cause male infertility through affection of spermatogenesis and
sperm quality. Strong evidences confirm that male infertility in metal-exposed humans is
mediated via various mechanisms such as production of reactive oxygen species (ROS). Flavonoids
have antioxidant and metal chelating properties which make them suitable candidates for neutralizing
adverse effects of metals on semen quality. In the current study, we have evaluated
the effects of five types of flavonoids (rutin, naringin, kaempferol, quercetin, and catechin) on
recovery of sperm motility and prevention of membrane oxidative damage from aluminum
chloride (AlCl3), cadmium chloride (CdCl2), and lead chloride (PbCl4).
Materials and Methods In this experimental study, motility and lipid peroxidation of metalexposed sperm was investigated
in the presence of different concentrations of five kinds of
flavonoids. Malondialdehyde (MDA) production was assessed as a lipid peroxidation marker. Results Aluminum chloride (AlCl3), cadmium chloride (CdCl2), and lead chloride
(PbCl4) diminished sperm motility. Treatment of metal-exposed sperm with rutin, naringin,
and kaempferol attenuated the negative effects of the metals on sperm motility.
Quercetin and catechin decreased the motility of metal-exposed sperm. Conclusion Based on the MDA production results, only AlCl3 significantly induced lipid peroxidation.
Treatment with rutin, naringin, and kaempferol significantly decreased
MDA production.

Abstract
OBJECTIVE Diabetes mellitus Type 2 is one of the most widespread chronic metabolic diseases. In most cases, this type of diabetes is associated with alterations in levels of some inflammatory cytokines and hormones. Considering anti-inflammatory properties of plant extracts rich in ascorbic acid (vitamin C) and alpha-tocopherol (vitamin E), anti-diabetic properties of these two well-known antioxidant vitamins were investigated through measurement of serum levels of high-sensitivity C-reactive protein (hs-CRP), insulin, leptin, tumor necrosis factor alpha (TNF-α), and serum amyloid A (SAA) in patients with diabetes mellitus type 2. MATERIALS AND METHODS Male patients (n=80) were randomly divided into two groups each consisted of 40 subjects. Test groups were supplemented with ascorbic acid (1000 mg/day) or alpha-tocopherol (300 mg/day) orally during four weeks. Before and after treatment, serum biochemical factors of subjects were measured and compared. RESULTS Our results showed that both ascorbic acid and alpha-tocopherol could induce significant anti-inflammatory effects by decreasing the level of inflammatory factors such as TNF-α, SAA, and hs-CRP in diabetes mellitus type 2 patients. Effects of alpha-tocopherol and ascorbic acid in decreasing serum leptin level were similar. Ascorbic acid in contrast to alpha-tocopherol diminished fasting insulin and HOMA index but had no effect on LDL serum level. CONCLUSION Concerning the obtained results, it is concluded that consumption of supplementary vitamins C and E could decrease induced inflammatory response in patients with diabetes mellitus type 2. It is also possible that vitamin C and vitamin E supplementation can attenuate incidence of some proposed pathological effects of diabetes mellitus.

Abstract
Trastuzumab (Herceptin(®) ) is a monoclonal antibody (mAb) for specific ablation of HER2-overexpressing malignant breast cancer cells. Intensification of antiproliferative activity of trastuzumab through construction of immunotoxins and nano-immunoconjugates is a promising approach for treatment of cancer. In this study, trastuzumab was directly conjugated to diphtheria toxin (DT). Also, conjugates of trastuzumab and multiwalled carbon nanotubes (MWCNT) were constructed by covalent immobilization of trastuzumab onto MWCNTs. Then, antiproliferative activity of the fusion constructs against HER2-overexpressing SK-BR-3 and also HER2-negative MCF-7 cancer cell lines were examined. Cells treated with trastuzumab-MWCNT conjugates were irradiated with near-infrared (NIR) light. Efficient absorption of NIR radiation and its conversion to heat by MWCNTs can be resulted to thermal ablation of cancerous cells. Our results strongly showed that both trastuzumab-MWCNT and trastuzumab-DT conjugates were significantly efficient in the specific killing of SK-BR-3 cells. Targeting of MWCNTs to cancerous cells using trastuzumab followed by exposure of cells to NIR radiation was more efficient in repression of cell proliferation than treatment for cancer cells with trastuzumab-DT. Our results also showed that conjugation linkers can significantly affect the cytotoxicity of MWCNT-immunoconjugates. In conclusion, our data demonstrated that trastuzumab-MWCNT is a promising nano-immunoconjugate for killing of HER2-overexpressing cancerous cells.

Abstract
Malfunction or overexpression of ErbB receptors (epidermal growth factor receptors) is associated with occurrence and severity of several types of cancer. Initiation of signal cascades by ErbB2 (also known as human epidermal growth factor receptor 2/neu) in breast cancer has been blocked by monoclonal antibodies such as Trastuzumab (Herceptin), which interact with the extracellular domain of human epidermal growth factor receptor 2. Due to some disadvantages of monoclonal antibodies, a new approach in blocking human epidermal growth factor receptor 2 dimerization and activation is designing peptidomimetic ligands based on human epidermal growth factor receptor 2-Trastuzumab interaction model. Growth of human epidermal growth factor receptor 2(+) SK-BR3 cells could be specifically inhibited by peptidomimetic herceptin-based peptidomimetic 5. In this study, herceptin-based peptidomimetic 5 was used as a benchmark peptidomimetic compound to perform a ligand-based virtual screening followed by structure-based screening by applying the molecular docking approach. The study aimed to explore more potent peptidomimetic molecules against extracellular part of human epidermal growth factor receptor 2. Our results showed that the newly designed peptidomimetic herceptin-based peptidomimetic n33B in comparison with herceptin-based peptidomimetic 5 binds more tightly to the extracellular domain of human epidermal growth factor receptor 2. Mechanistic aspects of herceptin-based peptidomimetic n33B interaction with human epidermal growth factor receptor 2 were more investigated through 20-ns molecular dynamic simulations. Additionally, a quantitative structure-activity relationships study was performed to develop a model for identification of structural determinants in herceptin-based peptidomimetic 5-based peptidomimetics.

Abstract
A series of new quinazoline derivatives has been recently reported as potent multi-acting histone deacetylase (HDAC), epidermal growth factor receptor (EGFR), and human epidermal growth factor receptor 2 (HER2) inhibitors. HER2 is one of the major targets for the treatment of breast cancer and other carcinomas. Three-dimensional structure-activity relationship (3D-QSAR) is a well-known technique, which is used to drug design and development. This technique is used for quantitatively predicting the interaction between a molecule and the active site of a specific target. For each 3D-QSAR study, a three-dimensional model is created from a large curve fit to find a fitting between computational descriptors and biological activity. This model could be used as a predictive tool in drug design. The best model has the highest correlation between theoretical and experimental data. Self-Organizing Molecular Field Analysis (SOMFA), a grid-based and alignment-dependent 3D-QSAR method, is employed to study the correlation between the molecular properties and HER2 inhibitory potency of the quinazoline derivatives. Before presentation of inhibitor structures to SOMFA study, conformation of inhibitors was determined by AutoDock4, HyperChem and AutoDock Vina, separately. Overall, six independent models were produced and evaluated by the statistical partial least square (PLS) analysis. Among the several generated 3D-QSARs, the best model was selected on the basis of its statistical significance and predictive potential. The model derived from the superposition of docked conformation with AutoDock Vina with reasonable cross-validated q(2) (0.767), non cross-validated r(2) (0.815) and F-test (97.22) values showed a desirable predictive capability. Analysis of SOMFA model could provide some useful information in the design of novel HER2 kinase inhibitors with better spectrum of activity.

Abstract
Bacterial lipopolysaccharide (LPS) has T-helper 1 (Th1) immunostimulatory activities but because of toxicity and pyrogenicity cannot be used as an adjuvant. Brucella abortus LPS has less toxicity and no pyrogenic properties in comparison to other bacterial LPS. In the current study, the immunostimulatory properties of B. abortus LPS were evaluated for its adjuvant activity. Tuberculin purified protein derivative (PPD) from Mycobacterium tuberculosis was extracted and after anion-exchange chromatography on Q-sepharose column, two fractions (17 and 23), which dominantly contained 30- and 70-kDa antigens, were collected for immunological studies. BALB/c mice were immunized with four different antigen preparations (BCG, PPD, 17th and 23rd PPD fractions) along with complete Freund's adjuvant or B. abortus LPS. The T-cell immune response of mice was assessed by measurement of Th1-type cytokine (IFN-γ) and Th2-type cytokines (IL-5 and IL-10) levels. Also, the humoral immunity was evaluated by measuring the specific IgG levels. Our results showed that immunization of mice with 17th PPD fraction along with B. abortus LPS can induce a Th1-type cytokine response characterized with a high IFN-γ/IL-5 ratio, while immunization with PPD or 23rd PPD fraction along with the same adjuvant resulted to a mixed Th1/Th2-type cytokine response.
