Background: Child morbidity in African countries including the Republic of Benin, is mostly attributed to parasitic infectious diseases involving malaria. Molecular disorder often underlies the vulnerability of children immune system to infectious diseases. This reduces the ability of immune system to combat appropriately exogen organisms including parasites larva, bacteria or viruses. GATA-3 is a nuclear protein expressed by immune cells and belongs to a family member of the lymphocyte CD4 lineage determining transcription factors inducible by retinoic acid. Thus, GATA3 is one of the main regulators of lymphocyte T-helper 2 (Th2) cell differentiation into mature CD4+ T cells that mediate immunity tocombat exogenmicroorganism involving plasmodium falciparum (pf). The objective of the study is to investigate if children with low or absence of GATA3 expression will be more vulnerable to pf infection and malaria. Methods: This study has received an institutional ethical approval.Preliminary study carried out on cell lysates of peripheral white blood cells isolated from blood samples used for pf counts in Benin Zonal hospital of Calavi/So-Ava diagnosis laboratory involving eighteen children (5-9 years) admitted for fever associated or not to malaria. Immunoblotting (western blot) technic was used to evaluate GATA3 expression in all samples.The presence of pf was determined with microscopic observation of blood thick smears stained with Giemsa. Results: Among the eighteen samples, normal expression of GATA3 was observed in ten, low expression in six while no expression was observed in two samples. Overall, seven samples were positive for pf counts ranging from 350-1500 per mm3 of red blood cells. Infection with pf was not observed in eleven samples. Conclusion: Immune system of children with low GATA3 and high level of pf count will be more vulnerable to infection. Thus, the absence of GATA3 transcription factor could influence the outcome of malaria disease and render children too weak to fight pf infection.The absence of GATA3 may also render them vulnerable to develop allergy or lymphoma in the future.

Abstract Background: Although the onset of inflammatory cascades may profoundly influence the nature of antibody responses, the interplay between inflammatory and humoral (antibody) immune markers remains unclear. Thus, we explored the reciprocity between the humoral immune system and inflammation and assessed how external socio-demographic factors may influence these interactions.Methods: From the AMORIS cohort, 5,513 individuals were identified with baseline measurements of serum humoral immune (immunoglobulin G, A & M (IgG, IgA, IgM)) and inflammation (C-reactive protein (CRP), albumin, haptoglobin, white blood cells (WBC), iron and total iron-binding capacity) markers measured on the same day. Correlation analysis, principal component analysis and hierarchical clustering were used to evaluate biomarkers correlation, variation and associations. Multivariate analysis of variance was used to assess associations between biomarkers and educational level, socio-economic status, sex and age.Results: Frequently used serum markers for inflammation, CRP, haptoglobin and white blood cells, correlated together. Hierarchical clustering and principal component analysis confirmed the interaction between these main biological responses, showing an acute response component (CRP, Haptoglobin, WBC, IgM) and adaptive response component (Albumin, Iron, TIBC, IgA, IgG). A socioeconomic gradient associated with worse health outcomes was observed, specifically low educational level, older age and male sex were associated with serum levels that indicated infection and inflammation.Conclusions: These findings indicate that serum markers of the humoral immune system and inflammation closely interact in response to infection or inflammation. Clustering analysis presented two main immune response components: an acute and an adaptive response, comprising markers of both biological pathways. Future studies should shift from single internal marker assessment to multiple humoral and inflammation serum markers combined, when assessing risk of clinical outcomes such as cancer.

The purpose of this research was to know the effect of breadfruit leaves flour in feed to blood profile and correlation between cholesterol, HDL and LDL of blood with meat cholesterol of maleTegal duck of 10 weeks old. The material used was Day Old Duck of male Tegal duck  as much as 120 heads with experimental research methods and Completely Randomized Design (CRD). There were 6 treatments: feed without breadfruit leaf powder, feed + breadfruit flour 3% / kg feed, feed + breadfruit flour 6% / kg feed, feed + breadfruit flour 9% / kg feed, feed + flour breadfruit 12% / kg feed, and feed + breadfruit flour 15% / kg feed. Each treatment was repeated 5 times and each replication consisted of 4 ducks. The variables observed were the number of red blood cells, white blood cells, HDL, LDL, blood triglycerides, correlation between cholesterol, HDL and LDL blood with meat cholesterol of male Tegal duck of 10 weeks old.  The result of the analysis showed that the supplementation of breadfruit leaves has significant effect (P <0,05) on the number of red blood cells, white blood cells, HDL, and blood triglyceride. There is a positive correlation between blood cholesterol with duck meat cholesterol which given breadfruit leaf powder. This research can be concluded that the supplementation of breadfruit leaf powder (Artocarpus altilis) can increase the number of red blood cells, white blood cells, blood HDL level but lowers blood cholesterol and triglyceride blood of male Tegal duck of 10 weeks old. Cholesterol meat is affected by blood cholesterol with regression coefficient of 0.780941, influenced by LDL (r = 0.407849), but negatively affected by HDL (r = -0.47022).

Rabbit is widely used as an experimental animal model in infectious and non-infectious diseases. The haematologic data can be helpful in evaluating the health status of animals over time. The aim of this study was to determine the levels of red blood cells (RBC), white blood cells (WBC) and differential leukocyte counts in 5 nulliparous and 5 multiparous females, i.e. in young and older animals, at mating and at delivery. The values of RBC did not change with age, but WBC and lymphocytes decreased with age, a -33% and a -60% less in multiparous females than nulliparous ones. Monocytes count was double at delivery than at mating. In conclusion, aging on the immune system is manifested as reduction in production of mature lymphocytes and as a result, older females would not respond to immune challenge as robustly as the young ones. Physiological status is only related to production of monocytes.

The elasticity of white blood cells (WBCs) provides valuable insight into the condition of the cells themselves, the presence of some diseases, as well as immune system activity. In this work, we describe a novel process of refined control of WBCs elasticity through a combined use of gold nanoparticles (AuNPs) and the microelectrode array device. The capture and controlled deformation of gold nanoparticles enriched white blood cells in vitro are demonstrated and quantified. Gold nanoparticles enhance the effect of electrically induced deformation and make the DEP related processes more controllable.

<span lang="EN-US">The conventional method for detecting blood abnormality is time consuming and lacks the high level of accuracy. In this paper a MATLAB based solution has been suggested to tackle the problem of time consumption and accuracy. Three types of blood abnormality have been covered here, namely, anemia which is characterized by low count of red blood cells (RBCs), Leukemia which is depicted by increasing the number of white blood cells (WBCs), and sickle cell blood disorder which is caused by a deformation in the shape of red cells. The algorithm has been tested on different images of blood smears and noticed to give an acceptable level of accuracy. Image processing techniques has been used here to detect the different types of blood constituents. Unlike many other researches, this research includes the blood sickling disorder which is epidemic in certain regions of the world, and offers a more accuracy than other algorithms through the use of detaching overlapped cells strategy.</span>

Polycythemia Vera (PV) is a slowly progressing blood cancer associated with myeloproliferative neoplasms. The disease is characterized by an abnormal proliferation of three cell types including red blood cells, white blood cells and platelets and a symptom of pruritus caused by release of itching agents of activated mast cells. The enhanced expression of several genes involved in immune system control including CTLA-4, PD-1 and LAG3 are linked to activation immune tolerance. Klotho gene has anti-aging, anti-inflammation and anti-cancer functions. The SHP gene group belongs to the tyrosine phosphatase protein signaling family that regulates cancer cell proliferation through maturation, migration and apoptosis and includes two main genes, SHP-1 and SHP-2. The increased serum content of cancer antigen CA125 is considered as a cancer marker of several blood and hematopoietic disorders. In this study, we conducted experiments to determine mRNA expression of above genes in PV patients by realtime-PCR and CA125 concentration by ELISA. Results showed that expression of klotho, LAG3, CTLA-4 and PD-1 genes was decreased in PV patients, indicating that the immune tolerance was inactivated in PV patients. CA125 concentration was significantly increased in PV patients compared to healthy individuals and interestingly, there was a positive association among three patients, who having increased CA125 concentration and biochemical indicators including LDH, AST and ALT. The results in this study provide an important reference document for further studies that serve for the early detection of PV disease.
