Detection of the SARS-CoV-2 Nucleocaspid Protein (NP) Using Immunohistochemistry

While FC Accessories lymphocytopenia is a common characteristic of patients infected by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the mechanisms responsible for this depletion are unclear.With the tissue samples of the spleens and lymph nodes (LNs) from six cases, immunohistochemistry demonstrated ACE2 (angiotensin-converting enzyme 2), the potential receptor of SARS-CoV-2, expresses on tissue-resident Belts CD169+ macrophages in spleens and LNs.
