Abstract
Canine parvovirus type 2 (CPV-2) is one of the most common causes of infectious diarrhea in small animals, with high mortality and morbidity. Information on the specific treatment option(s) for CPV diseases (CPVD) is unachievably little. So, the treatment is mainly supportive one. Disruption of dog's innate immune system in viral diseases simply occurs; presumably, the CPV-2 may change the level of some TLRs, interleukins, CD4 and CD8 in the leukocytes of CPVD dogs, and disruptive activities of these immune molecules might be attributable to severe CPVD in dogs. Study on the role of the key immune molecules in CPVD is rare. Herein, by conducting and relating the clinical, para-clinical, immunological and molecular diagnostic tests, we tried to establish how some key immune molecules behave in blood of parvovirus affected dogs. As such, in the 1st study, the mRNA levels of TLR2, TLR4, TLR9, IL-1β, IL-6, CD4 and CD8 genes in the leukocytes of CPVD were assessed with quantitative (q)RT-PCR along with CPV-2 detection by rapid immunochromatography and PCR tests. In a 2nd study, the same measurements as in the 1st study were evaluated in two groups of mild versus severe clinical signs of CPVD. Both in the 1st and the 2nd studies leukopenia, much more pronounced in the severe CPVD, and immune dysregulation were observed. In the 1st study, a noticeable increase in the mRNA levels of TLR2 and TLR4 was detected with a slight decrease in TLR9 and a significant decrease in the expression of IL-1β, IL-6, CD4 and CD8 in leukocytes of CPV-infected dogs. Compared to the mild CPVD, the intense of downregulating effects on those immune molecules in the 2nd study was remarkably much more pronounced in the severe CPVD. Overall, it proves strong immune dysregulation and suppression/incompetence and potential T-cells exhaustion in severely CPV-2-affected dogs. Technically and clinically, this would be substantially applicable in canine medicine. By targeting those key immune molecules and their signaling pathways, new clinicodiagnostic approaches for CPVD can be evolved, and biotechnicoclinically this would be substantially applicable in all physiopathological conditions of dogs.

Abstract
Background Identification of plasma cells into abnormal (APC) and normal (NPC) compartments is of utmost importance in flow cytometric (FC) analysis of multiple myeloma (MM) and related plasma cell dyscrasias for diagnosis, prognosis, and follow-up. No single phenotypic marker is sufficient to distinguish NPC from APC. Materials and Methods 43 newly diagnosed cases of MM and 13 controls were included in the study. Bone marrow (BM) samples from the 2nd pass were processed on the same day with antibodies against CD38, CD138, CD19, CD81, CD45, CD117, CD200, CD56, cytoKappa, and cytoLambda in a 4-color experiment with CD38 and CD138 as gating antibodies. Results Mean APC% in cases was 96.5%. The expected Immunophenotype (IP) of APC which is CD19-/56+/45-/81-/117+/200+ was found in only 13/43 MM cases. In 30/43 cases, APC revealed deviation from expected IP either for single or a combination of markers. Sensitivity for APC detection was highest for CD19 (95.2%) followed by CD56 (90.4%) and CD81 (83.7%). Specificity was highest for CD19 (100%), CD56 (100%), and CD81 (100%) followed by CD117 (92.3%). Combination of markers with maximum sensitivity to detect APC (97.6%) was CD81- or CD19- and CD200+ or CD56+ (two markers); and for NPC (92.3%) was CD81+ and CD19+ and CD56- (three markers). Conclusion Plasma cell IP can be highly variable with multiple minor subpopulations in both cases and normal controls. CD 19 and CD56 are highly informative markers for a 4-color experiment. Assessment of multiple markers in an 8-10 color experiment is more informative but the lack of advanced flow cytometers should not limit the use of FC in a 4-color approach. Our results emphasize that even basic equipment with limited fluorochrome can provide meaningful information if used appropriately.

Abstract
The clusters of differentiation (CD) are surface molecules used for immunophenotyping of cells. The expression of CD markers is widely used to classify hematological malignancies, including leukemia and lymphoma. Single nucleotide polymorphisms (SNPs) are crucial genetic changes that can be associated with abnormal expression and function of CD markers. In this paper, we assess the prognostic effect of CD markers’ SNPs in hematological malignancies. Materials and methods and relevant literature was identified by a PubMed search (2001-2019) of English language papers using the following terms: ‘polymorphism’, ‘CD marker’, ‘leukemia’, ‘lymphoma’, ‘prognosis’, ‘CD marker’, and ‘polymorphism’. Many studies have demonstrated the effects of CD markers’ polymorphisms on risk of hematological malignancies. Also, SNPs of CD markers can be related with clinicopathological features, invasiveness, and response to therapy of these disorders. Considering the importance of SNPs in the expressions of CD markers, these genetic changes could be used as potential prognostic biomarkers in hematological malignancies. It is hoped that the evaluation of SNPs in CD markers will enable early diagnosis, prognosis, and detection of response to treatment. However, better understanding of SNPs in CD markers that are involved in hematological malignancies requires further studies on different populations of the worldwide.

Abstract
The aim of this study was to identify the cell surface cluster of differentiation (CD) markers of the cell lines infected by Theileria annulata schizont. The CD molecules are very useful for the characterization of cells and different subpopulations of leukocytes. They are usually recognized by specific antibodies using flow cytometry and immunohistochemistry. In the current study, we applied reverse transcriptase-polymerase chain reaction (RT-PCR) to define the profile of cell surface markers in a cell line infected by an attenuated S15 vaccine strain of T. annulata schizont and a new laboratory-established cell line infected by a non-attenuated form. In order to determine the specific markers that can be used for excluding the non-attenuated cell lines, the characterization of the surface proteins profile of the S15 vaccine cell line is important. The RT-PCR was carried out by specifically designed primers using a panel of seven bovine CD markers, as well as beta-actin as an internal control house-keeping gene. We showed that both of the examined cell lines had a consistent expression of CD4, CD5, CD11a, CD14, CD43, and CD45 markers. However, the specific finding in this study was the expression of B-cell markers CD79a and CD5 by the newly-transformed cell line. On the other hand, CD5 as a marker for B-cell subset was expressed by S15 vaccine strain. In conclusion, we consider CD79a surface protein as a new marker for the cell lines infected by non-attenuated T. annulata schizont, while the cell lines infected by the vaccine strain do not express this marker. In addition, the identification of CD marker expression based on the RT-PCR assay might be a suitable and appropriate alternative technique for flow cytometry.

Abstract
Polymorphonuclear neutrophils (PMNs) are the most common leukocytes in the circulation and exhibit a wide range of distinct cellular phenomena as part of their microbicidal killing activities, including degranulation, phagocytosis, reactive oxygen species (ROS) production, adhesion, chemotaxis and production of PMN Extracellular Traps (NETs). As a simple in vitro test of PMN functional responses in human blood we have developed a multicolor flow cytometry-based assay of PMN cluster of differentiation (CD) surface marker expression. Short incubations of whole human blood can be performed in the presence of a wide range of agonists or inhibitors, followed by sensitive detection of changes in CD marker expression. This protocol has the advantage that small amounts of human blood are necessary and there are no PMN isolation steps, which can alter PMN activation status.

Abstract
CD molecules are surface molecules expressed on cells of the immune system that play key roles in immune cell-cell communication and sensing the microenvironment. These molecules are essential markers for the identification and isolation of leukocytes and lymphocyte subsets. Here, we present the results of the first phase of the CD Maps study, mapping the expression of CD1–CD100 (n = 110) on 47 immune cell subsets from blood, thymus, and tonsil using an eight-color standardized EuroFlow approach and quantification of expression. The resulting dataset included median antibody binding capacities (ABCs) and percentage of positivity for all markers on all subsets and was developed into an interactive CD Maps web resource. Using the resource, we examined differentially expressed proteins between granulocyte, monocyte, and dendritic cell subsets, and profiled dynamic expression of markers during thymocyte differentiation, T-cell maturation, and between functionally distinct B-cell subset clusters. The CD Maps resource will serve as a benchmark of antibody reactivities ensuring improved reproducibility of flow cytometry-based research. Moreover, it will provide a full picture of the surfaceome of human immune cells and serves as a useful platform to increase our understanding of leukocyte biology, as well as to facilitate the identification of new biomarkers and therapeutic targets of immunological and hematological diseases.

Abstract
Several surface markers have been proposed for the identification and characterization of colorectal cancer stem-like cells (CR-CSLCs). However, their reliability in CR-CSLCs identification remains controversial. This study evaluated the correlation between all candidate surface marker's expression and CSLCs properties (tumorigenicity) through monitoring in vivo tumor incidence and final tumor volume. PubMed, Web of Science, and Scopus databases were systematically searched until November 2017. A total of 27 studies were found that met the inclusion criteria for cluster of differentiation 133 (CD133) and CD44 markers. Results indicated that either CD133 or CD44 positive cells caused about twofold increase in tumor volume compared with the negative cells (p < 0.05). In two groups of cells derived from primary tumors and cell lines, CD133 + cells had 25 and 1.45 times higher tumor incidence potential than CD133 - cells, respectively ( p < 0.05). Also, cohort evaluation showed that CD133 overexpression at protein level is a marker of poor overall survival in colorectal cancer (CRC) patients. While CD44 + cells displayed twofold tumorigenicity compared with the negative cells ( p < 0.05), combination of CD44 and CD133 showed about sevenfold tumorigenicity potential ( p < 0.05). In conclusion, the present meta-analysis suggests that CD133 is a robust biomarker to identify primary tumor CSLCs and can be proposed as a prognostic marker of CRC patient whereas it should be used with caution in cell lines. It seems to be more reliable to use CD133 in combination with CD44 as target biomarkers for the isolation of CR-CSLCs in both cell line and primary tumor cells populations.

Abstract
Background Mesenchymal Stromal/Stem Cells (MSCs), isolated under the criteria established by the ISCT, still have a poorly characterized phenotype that is difficult to distinguish from similar cell populations. Although the field of transcriptomics and functional genomics has quickly grown in the last decade, a deep comparative analysis of human MSCs expression profiles in a meaningful cellular context has not been yet performed. There is also a need to find a well-defined MSCs gene-signature because many recent biomedical studies show that key cellular interaction processes (i.e. inmuno-modulation, cellular cross-talk, cellular maintenance, differentiation, epithelial-mesenchymal transition) are dependent on the mesenchymal stem cells within the stromal niche. Results In this work we define a core mesenchymal lineage signature of 489 genes based on a deep comparative analysis of multiple transcriptomic expression data series that comprise: (i) MSCs of different tissue origins; (ii) MSCs in different states of commitment; (iii) other related non-mesenchymal human cell types. The work integrates several public datasets, as well as de-novo produced microarray and RNA-Seq datasets. The results present tissue-specific signatures for adipose tissue, chorionic placenta, and bone marrow MSCs, as well as for dermal fibroblasts; providing a better definition of the relationship between fibroblasts and MSCs. Finally, novel CD marker patterns and cytokine-receptor profiles are unravelled, especially for BM-MSCs; with MCAM (CD146) revealed as a prevalent marker in this subtype of MSCs. Conclusions The improved biomolecular characterization and the released genome-wide expression signatures of human MSCs provide a comprehensive new resource that can drive further functional studies and redesigned cell therapy applications.

Abstract
BACKGROUND Acute leukemia is a heterogenous disease having diverse phenotypes. Immunophenotyping by flowcytometry is essential for diagnosis of myeloid and lymphoid subtypes. Aberrant phenotype incidence is controversial and dissimilar results have been reported by different groups. OBJECTIVES Purpose of the study was to determine the incidence of aberrant phenotypes in North East Indian patients with acute leukemia. METHODS We analysed a total of 100 cases (AML = 36, ALL = 61, MPAL = 3) by multiparametric flow cytometry using an acute panel of monoclonal antibodies (MoAbs). The MoAbs were selected to identify differentiation-associated antigens of both myeloid and lymphoid lineages. RESULTS Aberrant phenotypes were found in 21 (58.3%) cases of AML, 36 (59.2%) cases of B-ALL and 6 (66.7%) cases of T-ALL. CD7 was the most frequent lymphoid associated antigen found in 33% of AML cases while CD117 was the myeloid antigen most frequently detected in ALL (54%) cases. Aberrant expression of CD 117 is highly significant by Fischer's exact test (P< 0.0001). CONCLUSION We conclude that aberrant phenotypes are present in a great majority of acute leukemia patients of North East India. Future studies will be directed to correlate of these markers with prognosis and therapeutic response.
