Naturally Occurring Co-infection of Avian Leukosis Virus (subgroups A-E) and Reticuloendotheliosis Virus in Green Peafowls (Pavo muticus)

Brazilian Journal of Poultry Science
Most of the neoplastic diseases affecting poultry have a viral etiology, such as Marek’s disease, avian leukosis/sarcoma and reticuloendotheliosis. In the present paper, histopathology and molecular methods were performed, in addition of necropsy and ...

The Genome of a Very Virulent Marek's Disease Virus

Journal of Virology, 2000
ABSTRACT Here we present the first complete genomic sequence, with analysis, of a very virulent strain of Marek's disease virus serotype 1 (MDV1), Md5. The genome is 177,874 bp and is predicted to encode 103 proteins. MDV1 is colinear with the prototypic alphaherpesvirus herpes simplex virus type 1 (HSV-1) within the unique long (UL) region ...

Silent pressure: Unveiling spinal lymphoma in horses and its parallels to other species

Equine Veterinary Education, Volume 38, Issue 5, Page 231-234, May 2026.
Summary Though the nervous system is an uncommon location for lymphoma, the disease should remain a differential diagnosis in some cases of ataxia in equids. Diagnosis of lymphoma can be challenging, although a combination of cytology, histopathology and immunophenotyping can aid in definitive diagnosis and therefore more accurately guide treatment and

Plasma proteomic profiling and molecular clustering reveal immune‐defined prognostic subtypes in lung adenocarcinoma

International Journal of Cancer, Volume 158, Issue 4, Page 858-865, 15 February 2026.
What's new? Lung adenocarcinoma shows considerable heterogeneity in disease progression and therapeutic response. Here, the authors analyzed tumor samples through proteomic profiling and applied network‐based clustering. They identified two distinct patient groups with different demographic, clinical, and molecular characteristics.

Wnt‐dependent spatiotemporal reprogramming of bone marrow niches drives fibrosis

HemaSphere, Volume 10, Issue 2, February 2026.
Abstract Bone marrow fibrosis is the most extensive matrix remodeling of the microenvironment and can include de novo formation of bone (osteosclerosis). Spatiotemporal information on the contribution of distinct bone marrow niche populations to this process is incomplete.

A novel protein-coding ORF72.2 gene was identified from Marek's disease virus strain CVI988

Virology Journal, 2010
Marek's disease is a highly contagious disease of poultry characterized by rapid-on set of T-cell lymphomas, which is caused by Marek's disease virus (MDV), but its pathogenic mechanism is still not very clear.
