Objective: To study the changes of T lymphocyte subsets and immunoglobulin in peripheral blood of patients with acute lymphoblastic leukemia (ALL) and non-acute lymphocytic leukemia (N-ALL) before and after treatment and their value for monitoring of disease and evaluation of prognosis.
Methods: One hundred and six cases of leukemia were selected in our hospital, including 48 cases of ALL (ALL group) and 58 cases of N-ALL (N-ALL group); 54 peoples of normal physical examination were selected as the normal control group in the same period. The IgA, IgG and IgM levels of peripheral blood were detected, and the absolute value of T lymphocyte subsets was determined by cell slide method. According to whether the patients' status was improved or not by treatment, the 106 patients were divided into the unimproved group (55 cases including 25 ALL, 30 N-ALL) and improved group (51 cases including 23 ALL, 28 N-ALL).
Results: The levels of IgA, IgG and IgM in 106 cases of leukemia were significantly lower than those in the control group (all P<0.05), and the CD3 level, CD3CD4/CD3CD8 ratio and the absolute value of CD3CD4T cells in the peripheral blood were significantly lower than those in the control group(all P<0.05); the absolute value of CD3CD8T cells showed no significant difference in comparison with the control group (P >0.05). After treatment, IgA,IgG and IgM levels in the improved group were significantly higher than those before therapy (all P<0.05), while their levels were not significantly different from that in the control group (all P>0.05); the CD3 level, CD3CD4/CD3CD8 ratio and the absolute value of CD3CD4T cells in the peripheral blood were significantly higher than those before therapy (all P<0.05), while those were not significantly different from the control group (all P>0.05). Compared with levels before treatment, the levels of above mentioned indicators in the unimproved group after treatment were not significantly different (all P>0.05); and the CD3 level, CD3CD4/CD3CD8 ratio and the absolute value of CD3CD4T cells were significantly lower than those in the control group (all P<0.05), and the absolute value of CD3CD8T cells were higher than that in the control group (P<0.05).
Conclusion: After the treatment, the T lymphocyte subsets (CD3, CD3CD4T cells) and immunoglobulin (IgA, IgG, IgM) levels in peripheral blood of patients with ALL and N-ALL have been improved significantly, and the detection of these indexes is helpful for disease monitoring and prognosis evaluation.

TSLP acts on regulatory T cells to maintain their identity and limit allergic inflammation.

Thymic stromal lymphopoietin (TSLP) is a type I cytokine that promotes allergic responses and mediates type 2 immunity. A balance between effector T cells (T), which drive the immune response, and regulatory T cells (T), which suppress the response, is required for proper immune homeostasis. Here, we report that TSLP differentially acts on T versus T to balance type 2 immunity.

Regulatory T cells (T) accumulate in the visceral adipose tissue (VAT) to maintain systemic metabolic homeostasis but decline during obesity. Here, we explored the metabolic pathways controlling the homeostasis, composition, and function of VAT T under normal and high-fat diet feeding conditions. We found that cholesterol metabolism was specifically up-regulated in ST2 VAT T subsets.

Objectives: To determine T helper (Th)1 and Th2 cytokine polarization, as well as high-sensitive cardiac troponin I (hs-cTnI) levels, in cats with pyometra.
Methods: We used 40 queens in the study. A total of 20 out of these 40 queens were diagnosed with the pyometra group (PYO) and the other 20 made up the healthy group (control; CTR).

Th/Th polarisation and suppressor of cytokine signalling-3 (SOCS3) are important indicators of the humoral and cellular immune system activity in cows. The aim of this study was to determine the correlation of postpartum diseases with the levels of Th/Th polarisation and SOCS3 at the time of parturition. The study examined 180 cows (90 with normal parturition [NP] and 90 with dystocia [D]).

Type 1 diabetes (T1D) is a complex disease driven by the immune system attacking the insulin-producing beta cells in the pancreas. Understanding the role of different T cell subpopulations in the development and progression of T1D is crucial. By employing flow cytometry to compare the characteristics of T cells, we can pinpoint potential indicators of treatment response or therapeutic inefficacy.
