B lymphocytes were purified from the peripheral blood of 30 B-cell chronic lymphocytic leukemia (B-CLL) patients and tested for the ability to produce granulocyte colony-stimulating factor (G-CSF) in vitro. Fifteen Staphylococcus aureus Cowan I (SAC)-stimulated, but not unstimulated, B-cell suspensions produced G-CSF in short-term cultures. Accordingly, G-CSF mRNA was detected only in SAC-stimulated B cells. Five CLL B-cell fractions that released G-CSF following exposure to SAC were also incubated with CD40 or anti-mu antibodies in the presence or absence of recombinant (r) interleukin-2 (IL-2) or IL-4. The 5 cell suspensions produced G-CSF only on culture with CD40 monoclonal antibody in combination with rIL-2 or rIL-4. CD5+ B lymphocytes, which represent the normal counterparts of most B-CLL proliferations, did not produce G-CSF under any of the above culture conditions. G-CSF produced by leukemic B lymphocytes was biologically active, because conditioned media of SAC-stimulated cells supported the in vitro growth of myeloid colonies from normal bone marrow progenitors. The colony stimulating activity of CLL B-cell supernatants was ascribed to both G-CSF and granulocyte-macrophage colony stimulating factor. G-CSF receptors (G- CSFRs) were detected on freshly isolated B lymphocytes from 7 of 11 B- CLL patients; 5 of these cell suspensions produced G-CSF in culture, whereas 2 did not. rG-CSF rescued 3 of the 7 G-CSFR+ cell fractions from spontaneous apoptosis but had no effect on their in vitro proliferation.

Abstract Plerixafor (AMD3100) and granulocyte colony-stimulating factor (G-CSF) mobilize peripheral blood stem cells by different mechanisms. A rhesus macaque model was used to compare plerixafor and G-CSF–mobilized CD34+ cells. Three peripheral blood stem cell concentrates were collected from 3 macaques treated with G-CSF, plerixafor, or plerixafor plus G-CSF. CD34+ cells were isolated by immunoselection and were analyzed by global gene and microRNA (miR) expression microarrays. Unsupervised hierarchical clustering of the gene expression data separated the CD34+ cells into 3 groups based on mobilization regimen. Plerixafor-mobilized cells were enriched for B cells, T cells, and mast cell genes, and G-CSF–mobilized cells were enriched for neutrophils and mononuclear phagocyte genes. Genes up-regulated in plerixafor plus G-CSF–mobilized CD34+ cells included many that were not up-regulated by either agent alone. Two hematopoietic progenitor cell miR, miR-10 and miR-126, and a dendritic cell miR, miR-155, were up-regulated in G-CSF–mobilized CD34+ cells. A pre-B-cell acute lymphocytic leukemia miR, miR-143-3p, and a T-cell miR, miR-143-5p, were up-regulated in plerixafor plus G-CSF–mobilized cells. The composition of CD34+ cells is dependent on the mobilization protocol. Plerixafor-mobilized CD34+ cells include more B-, T-, and mast cell precursors, whereas G-CSF–mobilized cells have more neutrophil and mononuclear phagocyte precursors.

Acetaminophen (APAP) is often used as an antipyretic and analgesic agent. Overdose hepatotoxicity, which often results in liver cell failure and liver transplantation, is a severe complication of APAP usage. To save the liver and save lives from acute liver damage caused by APAP, the search for new strategies for liver defense is important. Wistar rats have been used for the induction of APAP hepatotoxicity. Elevated levels of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) were evaluated for liver toxicity. In addition, the levels of hepatic tissue oxidative markers such as malondialdehyde (MDA), nitric oxide (NO) increased while glutathione (GSH) was depleted and catalase (CAT) activity was curtailed. The biochemical findings were consistent with the changes in histology that suggested liver damage and inflammation. Treated rats with N-acetylcysteine (N-AC) and granulocyte colony stimulating factor (G-CSF) showed a decrease in serum levels of ALT, AST and LDH, while the level of ALP in the G-CSF group was still high. After administration of APAP, treatment with N-AC or G-CSF substantially reduced the level of MDA and NO while maintaining the GSH content and CAT activity. Treatment with N-AC and G-CSF after administration of APAP has also attenuated inflammation and hepatocytes necrosis. The results of this study showed that G-CSF could be viewed as an alternative hepatoprotective agent against APAP-induced acute liver injury compared to N-AC.
