During viral infection, phagocytic cells participate in numerous immunological processes. A common approach to elucidate the specific contributions of phagocytic cells is through direct comparison of viral pathogenesis of phagocyte-depleted and phagocyte-intact animals. Clodronate liposomes are a versatile and simple means of depleting phagocytes in any animal model. Selection of clodronate liposome route of delivery can yield systemic or local phagocyte depletion as needed. Here we describe the application of clodronate liposome-mediated depletion of blood-contacting phagocytes to investigate their interactions with La Crosse virus (or other bunyaviruses) in a reductionist model of viremia.

Obesity is concurrent with immunological dysregulation, resulting in chronic low-grade inflammation and cellular dysfunction. In pancreatic islets, this loss of function has been correlated with mature β-cells dedifferentiating into a precursor-like state through constant exposure to inflammatory stressors. As mature adipocytes likewise have the capability to dedifferentiate in vitro and in vivo, we wanted to analyze this cellular change in relation to adipose tissue (AT) inflammation and adipose tissue macrophage (ATM) activity.

Recently approved adeno-associated viral (AAV) vectors for liver monogenic diseases haemophilia A and B are exemplifying the success of liver-directed viral gene therapy. In parallel, additional gene therapy strategies are rapidly emerging to overcome some inherent AAV limitations, such as the non-persistence of the episomal transgene in the rapidly growing liver and immune response. Viral integrating vectors such as in vivo lentiviral gene therapy and non-viral vectors such as lipid nanoparticles encapsulating mRNA (LNP-mRNA) are rapidly being developed, currently at the preclinical and clinical stages, respectively.

Dry eye disease (DED) is a prevalent ophthalmic disease that affects millions of people worldwide. Iron overload and macrophage inflammation have been implicated in the development of murine DED, though the specific role of macrophages under iron overload conditions remains unclear. This study aimed to establish a novel iron overload-induced mouse model of DED and investigate macrophage involvement.

Introduction: Acute lung injury (ALI) and its subsequent progression to acute respiratory distress syndrome (ARDS) are severe respiratory conditions. They are marked by rapid lung function deterioration and extensive pulmonary inflammation, often resulting in critical patient outcomes. Alveolar macrophages (AMs) and monocyte-derived macrophages (MDMs) are two distinct subsets of lung macrophages present in the alveoli during ALI.
