In recent years increasing evidence proposed that local immune cells at implantation site have largely contributed to embryo implantation. The intrauterine infusion of activated peripheral blood mononuclear cells culture 2 days before embryo transfer can enhance the implantation. One of the methods used to evaluate the endometrial receptivity is by assessing the sub endometrial blood flow. A total of 67 infertile women (30) women receives intrauterine non-invasive insemination of peripheral blood mononuclear cells (PBMC) culture 2 days before embryo transfer representing the PBMC test group, and (37) women without receiving any cell as Non-PBMC group. The cultured PBMC are administered into the uterine cavity of the patients. 2 days later, embryos are transferred into the uterine cavity. Endometrial thickness and sub-endometrial blood flow measurements are taken for all cases on trigger and embryo transfer days. On embryo transfer day there was no significant difference (p = 0.770) in mean endometrial thickness between the PBMC group and Non-PBMC group. There was a significant difference (p< 0.001) in the mean resistive index; the level being lower in the PBMC group. Moreover, there was a significant difference (p< 0.001) in the mean pulsatility index. Regarding all enrolled women, the pregnancy rate of 25.4 %, the rate was higher in the PBMC group in comparison with the Non-PBMC group, 43.3 % versus 10.8 %, respectively and the difference was significant (p = 0.002). The use of PBMC culture can improve sub-endometrial.

Study objective. To evaluate the efficacy of intrauterine administration of autologous peripheral blood mononuclear cells (PBMC) prior to embryo transfer in patients with recurrent implantation failures in IVF program. Materials and methods. The study enrolled 129 patients with recurrent implantation failures in an IVF programme. Group 1 - 42 patients who had intrauterine administration of autologous PBMC activated with hCG (Pregnyl 500 IU). Group 2 - 42 patients who had intrauterine administration of autologous PBMC without hCG activation. Group 3 (placebo) - 45 patients who had intrauterine administration of saline. Study results. In the hCG-activated PBMC group, the rates of positive blood hCG tests, implantation, and clinical pregnancy were significantly higher than the respective rates in the non-activated PBMC group and in the placebo group, both in a stimulated cycle and in an FET cycle (р≤0.05). Conclusion. Intrauterine administration of autologous PBMC prior to embryo transfer in an IVF/ICSI programme increases the efficacy of IVF program in patients with a history of recurrent implantation failures.

Lymphocyte Phenotypes

Canine transmissible venereal tumor (CTVT) is a tumor which can be transmitted naturally through mucosa contact between dogs. When CTVT cells are experimentally inoculated on dogs, they will grow rapidly (Progressive/P phase) and then regress (Regressive/R phase) spontaneously. Therefore, it is a good model to investigate the interactions between tumor cells and host immune system. Previous studies have shown that CTVT cells cannot grow in the dogs restored from CTVT inoculation. To investigate the possible mechanism, this study characterized the CTVT-specific immune response of the peripheral blood mononuclear cells (PBMCs) which isolated from the blood of "naïve" or "CTVT-restored" dogs. The phenotypes (CD3, CD4, CD8, or CD21) of PBMCs were examined by flowcytometry. In response to CTVT stimulation, proliferation, IFN-γ secretion, and cytotoxicity of PBMCs were analyzed. Expression level of proinflammatory cytokines (TNF-α, IL-1β, IL-6, TGF-β), Th1 (IL-2, IFN-γ), and Th2 cytokines (IL-4, IL-10) and cytotoxic proteins (Granzyme B, Perforin) in PBMCs was also evaluated by real-time RT-PCR. The results indicated that there is no significant difference between two groups on lymphocyte phenotypes. Proliferation, IFN-γ secretion, and cytotoxicity of PBMCs between two groups showed no significant difference, except naïve PBMCs present higher proliferation after Con-A stimulation. Production of IL-1β and IL-6 in naïve PBMCs was higher than that in CTVT-restored PBMCs (p < 0.05). The production difference of IL-1β and IL-6 between two groups might be the reason why CTVT cannot be reinoculated on CTVT-restored dog. However, further investigations are necessary to explore the exact role of these cytokines in CTVT growth.

Implantation Success

SummaryImplantation failure is a major limiting factor in assisted reproduction improvement. Dysfunction of embryo–maternal immuno-tolerance pathways may be responsible for repeated implantation failures. This fact is supported by immunotropic theory stipulating that maternal immune cells, essentially uterine CD56+ natural killer cells, are determinants of implantation success. In order to test this hypothesis, we applied endometrium immuno-modulation prior to fresh embryo transfer for patients with repeated implantation failures. Peripheral blood mononuclear cells were isolated from repeated implantation failure patients undergoing assisted reproductive technology cycles. On the day of ovulation induction, cells were isolated and then cultured for 3 days and transferred into the endometrium cavity prior to fresh embryo transfer. This immunotherapy was performed on 27 patients with repeated implantation failures and compared with another 27 patients who served as controls. Implantation and clinical pregnancy were increased significantly in the peripheral blood mononuclear cell test versus control (21.54, 44.44 vs. 8.62, 14.81%). This finding suggests a clear role for endometrium immuno-modulation and the inflammation process in implantation success. Our study showed the feasibility of intrauterine administration of autologous peripheral blood mononuclear cells as an effective therapy to improve clinical outcomes for patients with repeated implantation failures and who are undergoing in vitro fertilization cycles.

Abstract Objectives Linoleic acid (LA) is the major fatty acid in cardiolipin (CL), a phospholipid important for mitochondria function. Increasing dietary LA elevates tetralinoleoyl CL (LA4 CL) in cardiac muscle of animals; however, it is not clear if dietary LA increases LA4 CL in humans. The aim of this study was to determine if daily consumption of a cookie made with a LA-rich oil for two weeks could alter LA4 CL in peripheral blood mononuclear cells (PBMC) in healthy adults. Methods In a double-masked placebo-controlled study, 84 healthy adults were randomly assigned to consume one cookie made with LA-rich grapeseed oil (LA-cookie) or one cookie made with oleic acid-rich (OA) safflower oil (OA-cookie), every day for two weeks.  Fasting blood samples were collected for analysis of PBMC cardiolipin species. Results Daily consumption of the LA-cookie for 2 weeks increased LA4 CL in PBMC, while consuming the OA-cookie did not alter LA4 CL (group x week interaction p &lt; 0.01).  LA3OA1 CL decreased in the LA-cookie group but was unchanged in the OA-cookie group (group x week interaction p &lt; 0.01).  There was no significant difference in the change of LA2OA2 CL or LA1OA3 CL between the groups. Conclusions Increasing LA intake through daily cookie consumption increased LA4 CL and altered other CL species in the PBMC of healthy adults.  Future studies are needed to assess if PBMC CL species may be a biomarker for CL species in other tissues and to determine if changes in CL species through increased dietary LA intake are associated with altered mitochondria function.

✓ Peripheral blood mononuclear cells from 11 glioma patients and 11 healthy control subjects were cultured in medium containing recombinant interleukin-2 for a period of 5 days. The cytotoxicity of these lymphokine-activated killer (LAK) cells was tested on chromium-51-labeled freshly prepared allogeneic glioblastoma cells, and on the cell lines K562 (natural killer cell (NK)-sensitive) and Daudi (NK-resistant). Peripheral blood mononuclear cells from all subjects showed high levels of cytotoxicity against these targets. There was no significant difference between the patients and the control group when LAK cytotoxicity was compared. Thus, although glioma patients are known to have depressed immunological reactivity, the cytotoxic capacity of LAK cells derived from glioma patients is similar to that of LAK cells from healthy control subjects. However, the glioma patients had significantly reduced numbers of mononuclear cells in their peripheral blood, possibly due to steroid treatment. Therefore, the volume of blood required to generate the same number of LAK cells was approximately three times larger from the glioma patients than from control subjects.

BACKGROUND: In tuberculosis infections, the immune system is weakened and cannot produce enough cytokines to against the infection. b-glucan is a potent immunomodulator that induces cytokine production in various bacterial infections. This study aimed to determine the effects of b-glucan on the production of interferon (IFN)-γ and interleukin (IL)-12 in peripheral blood mononuclear cells (PBMCs) induced by Mycobacterium tuberculosis DNA.METHODS: PBMCs were isolated from 11 healthy subjects. PBMCs were treated with/without 5 μg/mL b-glucan and M. tuberculosis rpoB wild-type or mutant DNA. The production of IFN-γ and IL-12 in the supernatant was performed with enzyme-linked immune-sorbent assay (ELISA).RESULTS: b-glucan increased significantly (p<0.05) IFN-γ of M. tuberculosis mutant DNA-induced PBMCs, M. tuberculosis wild-type DNA-induced PBMCs, and non-induced PBMCs. b-glucan also increased significantly (p<0.05) IL-12 of M. tuberculosis mutant DNA-induced PBMCs, M. tuberculosis wild-type DNA-induced PBMCs, and non-induced PBMCs. There were not any significant difference between male and female groups for IL-12 and IFN-γ in all treatment groups (p>0.05, ANOVA test).CONCLUSION: This in vitro study indicates that b-glucan increases the performance of PBMCs to produce IFN-γ and IL-12, with/without induction of M. tuberculosis wild-type/ mutant DNA.KEYWORDS: b-glucan, IFN-γ, IL-12, M. tuberculosis, rpoB

Heterocyclic amines (HCAs) are a set of food contaminants that may exert a cytotoxic effect on human peripheral blood mononuclear cells (PBMC). However, the genetic mechanism underlying the cytotoxicity of HCAs on PBMC has not been investigated. In the study, bioinformatic analysis on gene dataset GSE19078 was performed. The results of weighted correlation network analysis and linear models for microarray and RNA-seq data analysis showed that four gene modules were relevant to 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) exposure while one gene module was correlated with 2-amino-3-methyl-3H-imidazo[4,5f]quinoline (IQ) exposure. Gene functional analysis showed that the five modules were annotated mainly with mRNA transcriptional regulation, mitochondrial function, RNA catabolic process, protein targeting, and immune function. Five genes, MIER1, NDUFA4, MLL3, CD53 and CSF3 were recognized as the feature genes for each hub gene network of the corresponding gene module, and the expression of feature genes was observed with a significant difference between the PhIP/IQ samples and the other samples. Our results provide novel genes and promising mechanisms for exploration on the genetic mechanism of HCAs on PBMC.
