Feline leukemia virus is a retrovirus that infects cats. FeLV can be transmitted from infected cats when the transfer of saliva or nasal secretions is involved.
Feline leukemia (or FeLV) is the leading viral killer of cats. It weakens the immune system, increases susceptibility to other diseases, causes blood disorders and is the most common cause of cancer in cats.

Feline Leukemia Virus (FeLV) is a retrovirus belonging to the coronavirus subfamily, which means it is a cancer-causing virus. FeLV only affects cats and cannot be spread to humans or other animals.

Moving forward, it's essential to keep these visual contexts in mind when discussing Feline Leukemia Cytokine Network Analysis.
Entry by retroviruses is mediated through interactions between the viral envelope glycoprotein and the host cell receptor(s). We recently identified two host cell proteins, FeLIX and Pit1, that are necessary for infection by cytopathic, T-cell-tropic feline leukemia viruses (FeLV-T).
