Background: Hepatocellular carcinoma (HCC) is the leading form of liver cancer and the second leading cause of cancer-related deaths globally. Exosomes in the HCC microenvironment can induce significant changes in natural killer (NK) cells during endocytosis. The present study aimed to distinguish exosomes in the blood of HCC patients, analyze changes in NK cell phenotype, and evaluate peroxidase and toluidine blue staining as alternative methods for observing the changes.

Methods: NK cells were collected from healthy donors, and exosomes were extracted from the blood of HCC patients. The exosomes were characterized in accordance with MISEV 2018 guidelines, and …

Infant nutrition and immune protection require the consumption of human milk, with macrophages mainly contributing to immune defense and infant development. This study was performed to investigate the correlation between macrophage cell numbers in human milk and various maternal factors. Thirteen human milk samples were collected from lactating mothers and were evaluated for macrophage cell numbers using a hemacytometer. The recorded questionnaire containing several questions, including age, multivitamin consumption, coronavirus disease 2019 vaccination status, allergy history, and lactation duration, was used to determine the maternal factors. Pearson’s correlation and Mann-Whitney test was employed in statistical analysis, with p-values < 0.05 considered significant. The macrophage cell number reached 54.236 ± 7.456 cells per mL. Notably, a significant correlation was observed between maternal allergy history and the number of macrophage cells in human milk (p …


Comparison Of Maturation Stages Of Natural Killer Cell Differentiation Culture From Cultured And Freshly Isolated Umbilical Cord Blood Hematopoietic Stem Cells, Samuel Febrian Wijaya, Retno Lestari, Inna Rahmawati, Imelda Rosalyn Sianipar, Robby Nuraditya, Iqbal Fasha, Gita Pratama, Radiana Dhewayani Antarianto Apr 2023

Background: Natural killer (NK) cells originate from the differentiation of hematopoietic stem cells (HSCs) in the common lymphoid progenitor pathway, and HSCs can be obtained from umbilical cord blood (UCB). Comparative studies of NK cell differentiation between cultured and freshly isolated HSCs are important in the development of NK cell therapy for cancer. This study aimed to compare the maturation stages of NK cell differentiation between cultured and newly isolated HSC samples using interleukin-2 in the absence of feeder cells.

Methods: Differentiation cultures were divided into two groups according to HSC source. Giemsa staining and flow cytometry were …

Syndrome Acute Respiratory Syndrome Corona Virus-2 (SARS COV2) is the virus that causes the COVID19 disease and has caused more than 4 million deaths worldwide. This virus infects the host cell through the interaction between the virus’s glycoprotein S molecule with the ACE2 which is the virus receptor, binding, undergoes membrane fusion and enters the cell and replicates in it. Currently, several strategies used in developing anti-viral compounds are targeting compounds that play a role in the process of entering the virus into host cells such as ACE2, S glycoprotein, and TMPRSS2, while some target main proteases such as RNA …
