Clozapine-induced agranulocytosis is documented in multiple studies, but there is limited literature on treatment-resistant agranulocytosis, the synergistic effect of multiple agranulocytosis-inducing drugs, and lithium's promyelocytic effects. This case highlights these gaps by discussing a patient with an absolute neutrophil count of zero while being treated with Depakote, Haldol, and clozapine. This case proposes more research on lithium's promyelocytic effects, especially in patients who are unresponsive or have a delayed response to discontinuing offending agents and granulocyte colony-stimulating factor (G-CSF).

Background: The treatment of all-trans retinoic acid (ATRA) and arsenical agent has revolutionarily improved the prognosis of acute promyelocytic leukemia (APL) both in adults and children. Nevertheless, coagulation disorder and differentiation syndrome (DS) are the main causes of early death in APL patients. Early chemotherapy to reduce leukocytes during induction is an important measure to reduce complications and mortality.

Background: The progression of leukemia is substantially associated with the interactions of leukemic cells with surrounding cells within the bone marrow microenvironment (BMM), and these interactions were facilitated using exosomes as vital mediators. The current study aimed to examine the proliferative effects of exosomes derived from the HL-60 cell line, a representative of acute myeloblastic leukemia (AML), on the cell cycle progression of human bone marrow mesenchymal stromal cells (hBM-MSCs), a key element of the BMM.
Methods And Results: hBM-MSCs were treated with different concentrations of AML-derived exosomes from the HL-60 cell line.

Background: Oncostatin M (OSM) is involved in several inflammatory responses. Tryptanthrin (TRYP), as a natural alkaloid, is a bioactive compound derived from indigo plants. Objectives/ Methods: The purpose of this study is to investigate the potential inhibitory activity of TRYP on OSM release from neutrophils using neutrophils-like differentiated (d)HL-60 cells and neutrophils from mouse bone marrow.

Inducing programmed cell death in tumors is a fundamental approach in cancer therapy, prompting extensive efforts to discover bioactive compounds with anticancer properties. , a plant used in traditional medicine across East Asia, has been reported to exhibit various biological activities, including anticancer effects. This study aimed to evaluate the apoptosis-inducing effects of methanol/dichloromethane (MeOH/CHCl) extracts of roots and their components in HL-60 human leukemia cells.

Spermatogonial stem cells (SSCs) sustain and modulate spermatogenesis through intricate signaling pathways and transcription factors. Promyelocytic leukemia zinc-finger (, also known as ) has been identified as a critical transcription factor influencing various signaling and differentiation pathways. plays a pivotal role in regulating the differentiation properties of SSCs and is essential for the proper maintenance of spermatogenesis.
