Abstract
The opposing roles of innate and adaptive immune cells in suppressing or supporting cancer initiation, progression, metastasis and response to therapy has been long debated. The mechanisms by which different monocyte and T cell subtypes affect and modulate cancer have been extensively studied. However, the role of B cells and their subtypes have remained elusive, perhaps partially due to their heterogeneity and range of actions. B cells can produce a variety of cytokines and present tumor-derived antigens to T cells in combination with co-stimulatory or inhibitory ligands based on their phenotype. Unlike most T cells, B cells can be activated by innate immune stimuli, such as endotoxin. Furthermore, the isotype and specificity of the antibodies produced by plasma cells regulate distinct immune responses, including opsonization, antibody-mediated cellular cytotoxicity (ADCC) and complement activation. B cells are shaped by the tumor environment (TME), with the capability to regulate the TME in return. In this review, we will describe the mechanisms of B cell action, including cytokine production, antigen presentation, ADCC, opsonization, complement activation and how they affect tumor development and response to immunotherapy. We will also discuss how B cell fate within the TME is affected by tumor stroma, microbiome and metabolism.

Abstract
Infection with Helicobacter pylori cytotoxin-associated gene A (CagA)-positive strains is associated with the development of gastric cancer (GC). However, some reports have failed to demonstrate an increased frequency of CagA antibodies in GC patients. This study evaluated the response of IgG antibody and subclasses IgG1 and IgG2 against both CagA and H. pylori membrane antigens in patients with pre-cancerous lesions and cases with GC. A total of 137 patients with a positive serum IgG response to H. pylori were selected: 46 with intestinal metaplasia, 41 with gastric adenocarcinoma and 50 with non-atrophic gastritis (NAG) considered as controls. The response of total IgG, IgG1 and IgG2 was investigated by immunoblot and ELISA using an in-house recombinant CagA and membrane antigens from a local strain, and possible associations were estimated using a logistic regression model. Compared with NAG patients, GC patients showed a higher frequency of IgG2 CagA antibodies (55.2 vs 15.4 %, P = 0.001), but a lower frequency (80.5 vs 96.0 %, P = 0.021) and diminished levels of IgG2 H. pylori antibodies [12.5 vs 21.9 ELISA units (EU), P = 0.007]. GC patients also presented lower levels of CagA (32.6 vs 42.4 EU, P = 0.004) and H. pylori total IgG (33.7 vs 38.7 EU, P = 0.029). GC was associated with a positive IgG2 CagA response [odds ratio (OR) = 3.74, 95 % confidence interval (CI) 1.81-5.37; P = 0.002] and with a low titre of total IgG CagA antibodies (OR = 2.18, 95 % CI 1.35-2.69; P = 0.006). These results suggest that the IgG2 response to CagA could be used as a novel serological marker to identify patients with H. pylori-associated GC.

Abstract
BACKGROUND The renal pathological manifestations of malignancy-associated membranous nephropathy (M-MN) and idiopathic membranous nephropathy (I-MN) are similar. It has been suggested that glomerular IgG4 deposition may play an important role in the pathogenesis of I-MN. In the present study, we compared the IgG subclass of immune complex deposition, clinical data and pathological data of patients with M-MN and I-MN. METHODS Eight patients with M-MN and 42 patients with I-MN diagnosed between 1997 and 2009 in our hospital were enrolled. The clinical and pathological data were retrospectively collected, and glomerular IgG subclass deposition was detected by immunohistochemistry. RESULTS Patients with M-MN were older (P = 0.003), with lower serum albumin (P = 0.034) and higher serum C-reactive protein (CRP) level (P = 0.003) than patients with I-MN. The majority of patients with M-MN had earlier pathological stages (P = 0.003) and less IgG deposition in glomeruli (P = 0.029). Absence of IgG4 deposition in glomeruli was notably observed in patients with M-MN (7/8 in M-MN versus 6/42 in I-MN, P < 0.001) and it was an independent predictor for occurrence of malignancy (hazard ratio 0.065, 95% confidence intervals 0.007-0.571, P = 0.014). CONCLUSION Absence of glomerular IgG4 deposition, together with older age, severe hypoalbuminemia and high serum CRP level could be useful clues to differentiate M-MN from I-MN.

Abstract
BACKGROUND Epidemiological studies have demonstrated strong links between Helicobacter pylori infection and gastric adenocarcinoma. Recent studies suggest that cell-mediated immunity influences the outcome of infection, including the development of gastric adenocarcinoma. The T-cell response can be characterized in terms of the secreted cytokine profile, which in turn influences the B-cell response including the balance of IgG subclass antibody. METHODS Serum anti-H. pylori IgG, IgG1 and IgG2 antibodies were studied by ELISA in subjects with benign gastric diseases, gastric dysplasia and gastric adenocarcinoma. RESULTS The distribution patterns of IgG subclass anti-H. pylori antibody varies significantly between H. pylori-linked benign and malignant disease in subjects infected with H. pylori. Significantly lower IgG2 levels were found in subjects with gastric adenocarcinoma compared with those with reflux esophagitis, chronic gastritis, gastric ulcer, and peptic ulcer, while IgG1 antibody remained at similar levels in both benign and malignant disease. A limited study of seropositive subjects with premalignant change was consistent with the fall in IgG2 antibody pre-dating malignant change, although pre-eradication results are needed to validate these data. CONCLUSIONS These studies indicate that subjects with low levels of IgG2 anti-H. pylori antibody are at risk of gastric adenocarcinoma, and that the previously described linkage between gastric adenocarcinoma and low total IgG antibody does not simply reflect reduced gastric colonization. The diagnostic value of this assay for pre-endoscopy screening is attractive.

Abstract
BACKGROUND Although childhood acute lymphoblastic leukemia (ALL) is highly responsive to chemotherapy, reliable techniques are needed to determine treatment outcome and predict impending relapse. In ALL, the cell surface over expression of 9-O-acetylated sialoglycans (9-OAcSGs) on lymphoblasts and concomitant high antibody titers in patients' sera was reported. OBJECTIVES The present study was aimed to evaluate whether anti-9-OAcSG titers can be harnessed to monitor the clinical outcome of ALL. DESIGN AND METHODS Anti-9-OAcSGs were analyzed by ELISA in children receiving either UK ALL X (n = 69, Group I) in India or UK ALL 97 (n = 47, Group II) in UK along with age-matched normal healthy controls at different time points over a period of >2 years. An attempt was also made to investigate subclass distribution of disease-specific IgG. Moreover, 17 patients having a higher sample size were longitudinally monitored. RESULTS Antibody levels were raised at disease presentation, decreased with remission induction, and importantly, reappeared with clinical relapse. Sera from patients with other hematological disorders and normal controls showed negligible levels of circulating anti-9-OAcSGs. In patients of both Groups I and II, the assay showed high sensitivity (98.92% and 96.77%) and specificity (92.1% and 95.91%), respectively. IgG subclass analyses during different phases of treatment revealed that 9-OAcSG-specific IgG(1) could serve as a better prognostic marker in ALL. CONCLUSIONS This study demonstrated the potential of this disease-specific antibody as an alternate marker in diagnosis and long-term assessment of ALL patients, suggesting its application in detection and prediction of impending relapse. Therefore, the expression of anti-9-OAcSGs, irrespective of their treatment protocol, may serve as an economical yet effective index for monitoring of childhood ALL.

Abstract
The diagnostic value of the decrease in percentage of immunoglobulin G1 (%lgG1) in breast cancer was analyzed with special emphasis on early tumor stages. IgG1 and total IgG were preoperatively measured in the sera of a total of 801 individuals using a modified quantitative affinity chromatography. Group A consisted of 174 healthy individuals of both sexes, group B of 324 female patients with benign breast disease, and group C of 303 patients with invasive and non-invasive breast cancer. Within group C, 13 patients presented with intraductal carcinoma, and 22 patients with a pT1a-tumour (diameter less than 0.5 cm). The %IgG1 values were compared among groups A, B and C. In addition, correlations were sought between %IgG1 values of group C and tumor size, stage (UICC), histopathological grade and oestrogen (ER) and progesteron receptor (PR) expression. The mean value of %IgG1 in group A was 63.3 +/- 0.5 s.e.m., in group B 57.75 +/- 0.4 s.e.m. and in group C 52.37 +/- 0.5 s.e.m. The differences of mean values were highly significant between all three groups. Sensitivity and specificity of %IgG1 to discriminate between group A and C were 75% and 87%, and between group B and C 62% and 63%, respectively. The significant decrease of %IgG1 in total serum IgG is able to distinguish patients with breast cancer of more than 5 mm in diameter from healthy controls and patients with benign breast diseases. Finally, calculated posterior probabilities revealed that within certain concentration limits %lgG1 may provide predictive information with high probabilities.

Abstract
BACKGROUND Previously, it could be demonstrated that human patients with malignant diseases of various tissues exhibited characteristic and highly significant changes in the serum patterns of immunoglobulin (Ig)G subclasses, consisting of a decrease in IgG1 and an increase in IgG2 relative to total IgG. The aim of the current study was to determine whether this phenomenon was detectable at the level of IgG-producing B lymphocytes. METHODS Using a competitive reverse transcriptase polymerase chain reaction specific to IgG1 and IgG2, the gene expression of these 2 IgG subclasses in peripheral B cells from 10 patients with carcinomas of various sites within the female reproductive tract and 10 healthy controls was quantitatively determined, in parallel with the concentrations of the respective serum proteins. RESULTS Absolute levels of IgG subclass messenger ribonucleic acid (mRNA) showed a slight but not significant decrease in IgG1 and an increase in IgG2 in patients with gynecologic malignancies. However, the ratio of IgG1 to IgG2 expression showed a highly significant (P < 0.001) decrease in tumor patients compared with healthy controls, and corresponded to the change in the ratio of IgG1 to IgG2 serum proteins. CONCLUSIONS These data suggest that the shifts in the serum patterns of IgG1 and IgG2 observed in patients with gynecologic malignancies are due to irregular biosynthesis of these IgG subclasses at the B-cell level.
