IL-3, IL-5, and GM-CSF are eosinopoietic cytokines that induce the proliferation and differentiation of eosinophils. However, the regulatory mechanism of eosinopoiesis is largely unknown. A combination of IL-3 and IL-5 induces selective proliferation and differentiation of eosinophils from mononuclear cell fractions of human cord blood. IFN-gamma decreases the IL-3- and IL-5-induced eosinophil differentiation in a dose-dependent manner. IL-4 and IL-2 also decrease the IL-3- and IL-5-induced eosinophil differentiation. These observations indicate that IL-2, IL-4, and IFN-gamma have a direct or indirect inhibitory effect on eosinopoiesis.

MAPK1IP1L::TFE3-rearranged renal cell carcinoma: a novel fusion adding to the differential diagnosis of oncocytic renal neoplasms.
Virchows Arch
January 2025
Department of Pathology, Stanford Medical Center, 300 Pasteur Drive, Stanford, CA, 94305, USA.
Beyond the more common TFE3 fusion partners PRCC, ASPSCR1, and SFPQ, additional less common fusion partners of TFE3-rearranged renal cell carcinoma (RCC) have been described. Herein, we present an example of TFE3-rearranged renal cell carcinoma harboring fusion partner MAPK1IP1L, a rare rearrangement with only one other reported tumor found in the literature. The currently reported TFE3-rearranged RCC demonstrates unique histological features compared to the previously reported tumor including dense eosinophilic cytoplasm and nuclear pseudoinclusions (corroborated by electron microscopic evaluation), with features not typically seen in other TFE3-rearranged RCCs.

Exacerbations of Chronic Obstructive Pulmonary Disease (COPD) have a substantial effect on overall disease management, health system costs, and patient outcomes. However, exacerbations are often underdiagnosed or recognized with great delay due to several factors such as patients' inability to differentiate between acute episodes and symptom fluctuations, delays in seeking medical assistance, and disparities in dyspnea perception. Self-management intervention plans, telehealth and smartphone-based programs provide educational material, counseling, virtual hospitals and telerehabilitation, and help COPD patients to identify exacerbations early.

Department of Respiratory Medicine, Juntendo University Faculty of Medicine and Graduate School of Medicine, Tokyo 113-8421, Japan.
Diffuse interstitial lung diseases (ILD) include conditions with identifiable causes such as chronic eosinophilic pneumonia (CEP), sarcoidosis (SAR), chronic hypersensitivity pneumonitis (CHP), and connective tissue disease-associated interstitial pneumonia (CTD), as well as idiopathic interstitial pneumonia (IIP) of unknown origin. In non-IIP diffuse lung diseases, bronchoalveolar lavage (BAL) fluid appearance is diagnostic. This study examines lymphocyte subsets in BAL fluid and peripheral blood of 56 patients with diffuse ILD, excluding idiopathic pulmonary fibrosis (IPF), who underwent BAL for diagnostic purposes.

WeYouVets, Ingrave, Essex CM13 3NU, UK.
Chronic coughing is a common complaint in small animal medicine and it has an extensive differential diagnosis with very different treatment and prognosis. Coughing is considered chronic when it lasts at least 8 weeks. This retrospective study aimed to describe the most common causes of chronic coughing in a population of dogs that presented to a referral hospital in England between January 2012 and December 2021.

Lancet Infect Dis

Human intestinal spirochaetosis is caused by the colonisation of the luminal membrane of the colon and rectum by anaerobic spirochaetes belonging to the genus Brachyspira. The common method used for its diagnosis is routine haematoxylin and eosin staining of colonic and rectal biopsy samples. The clinical spectrum of human intestinal spirochaetosis is heterogeneous, ranging from asymptomatic colonisation to symptoms such as chronic mucosal diarrhoea, rectal bleeding, and abdominal pain.
