Macrophages are found in tissues throughout the body and are important immune cells, however, these tissue macrophages are difficult to collect and study. Therefore, the ability to differentiate macrophages from peripheral blood precursors is an important research tool. Macrophage differentiation has been well studied in humans, but differentiation in the non-human primate is poorly characterized. Using human models is not always feasible for invasive experimental studies and, therefore, developing reliable protocols for the non-human primate model is important. We describe a method to differentiate macrophages in vitro in the rhesus monkey by culturing adherent peripheral blood mononuclear cells for five days in RPMI-1640 supplemented with 1% human serum, M-CSF, and IL-1beta. The resulting cells had a distinct macrophage phenotype, the ability to secrete cytokines in response to LPS, and antigen uptake and processing capabilities.

Introduction: Elbow ailments are common, but conventional treatment modalities have shortcomings, offering only interim pain relief rather than targeting the underlying pathophysiology. The last two decades have seen a marked increase in the use of autologous peripheral blood-derived orthobiologics (APBOs), such as platelet-rich plasma (PRP), to manage elbow disorders. Platelet-rich plasma (PRP) is the most widely used APBO, but its efficacy remains debatable.

The present study aims to examine the effect of 4 h of continuous sitting on cerebral endothelial function, which is a crucial component of cerebral blood flow regulation. We hypothesized that 4 h of sitting may impair cerebral endothelial function similarly to how it affects lower limb vasculature. Thirteen young, healthy participants were instructed to remain seated for 4 h without moving their lower limbs.

The incidence of invasive pulmonary aspergillosis (IPA) in non-neutropenic patients is increasing. This study aimed to evaluate the clinical outcomes and risk factors for mortality in non-neutropenic IPA patients. We conducted a prospective, multicenter study from August 2020 to February 2024, enrolling 565 patients with suspected IPA.

Background: Krabbe disease (KD; globoid cell leucodystrophy) is a rare autosomal recessive lipid storage disorder that affects the white matter of the peripheral and central nervous. Late-onset KD is less frequently diagnosed and often presents with milder symptoms, making accurate diagnosis challenging, especially when distinguishing it from peripheral neuropathy. In this report, we present two cases of late-onset KD in a Chinese family.

Background: Stroke remains a leading cause of mortality and disability among adults. Given the restricted therapeutic window for intravascular interventions and neuroprotection during the acute phase, there has been a growing focus on tissue repair and functional recovery in the subacute and chronic phases after stroke. The pro-inflammatory microglial polarization occurs in subacute and chronic phases after stroke and may represent therapeutic targets for stroke recovery.
